This page collects published third-party research for 13 questions. 8 have no reliable published benchmark as of October 2026. None of these figures are Revspire results. Vendor numbers are labelled with their evidence type.
Which sales skills score lowest in AI role-plays?
No reliable published benchmark exists as of October 2026.
No published role-play score data exists. The largest dataset on sales skills comes from Objective Management Group’s assessments, which compare top and bottom performers.
Proxy evidence
- Across 1.1M+ salespeople assessed by OMG, the biggest gap between top and bottom performers, 36% in average scores, spans five competencies taken together: comfort discussing money, taking responsibility, qualifying, selling value rather than price, and hunting for new business.Objective Management Group data (Dave Kurlan, CustomerThink), 2017 · Independent research-firm survey · 1,100,000+ salespeople from 11,000+ companies
How to measure this in your team: Rank rubric criteria by average role-play score across reps. Report the bottom three, by role and tenure.
How many discovery questions do top-scoring reps ask in a first call?
Between 11 and 14 questions in a discovery call is linked to the best outcomes in Gong’s analysis of recorded calls. The data is from 2017 and comes from live calls, not practice sessions.
Best available evidence
- Across 519,000 discovery calls, asking 11–14 questions correlated with the greatest success, and the most effective calls uncovered 3–4 business problems.Gong Labs (Chris Orlob), 2017 · Vendor platform data · 519,000 recorded discovery calls
How to measure this in your team: Count the questions buyers answered in recorded first calls. Compare the distribution for won and lost opportunities.
What talk-to-listen ratio do reps show in practice vs live calls?
For live calls, Gong’s widely cited ideal is 43:57, meaning the rep talks 43% of the time. No published data covers practice sessions, so the practice-versus-live comparison cannot yet be answered.
Best available evidence
- In 25,537 B2B sales conversations recorded in H1 2016, the ideal talk-to-listen ratio was 43:57. Most reps spoke for 65–75% of the call.Gong Labs (Chris Orlob), 2017 · Vendor platform data · 25,537 B2B sales conversations from 17 companies, recorded in H1 2016
How to measure this in your team: Report the median rep talk share in AI role-plays and in live calls for the same reps and call type.
Do practice scores predict win rate?
No reliable published benchmark exists as of October 2026.
No published sales study links practice scores to win rate. Research on organisational training shows that well-designed training changes on-the-job behaviour and results, on average.
Proxy evidence
- A meta-analysis of 397 effect sizes found training effects of about d = 0.62 on job behaviour and on organisational results.Arthur, Bennett, Edens & Bell, Journal of Applied Psychology 88(2), 2003 · Peer-reviewed academic study · Meta-analysis of 397 effect sizes from 162 sources
How to measure this in your team: Correlate each rep’s average practice score over a quarter with their win rate in the following quarter, controlling for segment.
How fast do sales skills decay without reinforcement (30/60/90 days)?
No reliable published benchmark exists as of October 2026.
No sales-specific skill-decay curve has been published. The forgetting curve is well replicated for memorised material, but the precise percentages often quoted for sales training could not be traced to a primary study.
Proxy evidence
- A 2015 replication of Ebbinghaus’s forgetting curve, with one participant over about 70 hours of learning and relearning word lists, produced results similar to the original curve, with an upward jump at the 24-hour point.Murre & Dros, PLOS ONE 10(7), 2015 · Peer-reviewed academic study · Single participant, about 70 hours of learning and relearning
- A 2018 CustomerThink post asserts that over 80% of what is taught is forgotten within 90 days, without citing a study.Dave Brock, CustomerThink, 2018 · Secondary citation (original not located) · Claim made without a cited study
How to measure this in your team: Re-test the same rubric at 30, 60 and 90 days after certification, without reinforcement, and report the score drop.
Which spaced-practice interval keeps scores highest?
No reliable published benchmark exists as of October 2026.
No sales study has tested practice intervals. Learning-science research gives a usable rule: the best gap between sessions grows with how long you need to remember, but shrinks as a share of that period.
Proxy evidence
- In a study of 1,354 adults, the optimal gap was about 20–40% of a one-week retention interval, falling to about 5–10% of a one-year interval. Well-chosen gaps improved recall by up to 111% against no gap.Cepeda, Vul, Rohrer, Wixted & Pashler, Psychological Science 19(11), 2008 · Peer-reviewed academic study · 1,354 adults; retention intervals of 7 to 350 days
How to measure this in your team: Randomise reps to two reinforcement intervals for the same skill, then compare scores 60 days later.
What share of reps practise voluntarily when it is not assigned?
No reliable published benchmark exists as of October 2026.
No published data exists on voluntary practice rates.
How to measure this in your team: Report the share of reps with at least one unassigned practice session in a month.
How many AI role-play sessions per week do top-quartile reps complete?
No reliable published benchmark exists as of October 2026.
No published data exists on practice frequency by performance quartile. Recommendations in vendor content are opinion.
How to measure this in your team: Report the median weekly role-play sessions for top-quartile reps, by attainment, against the median rep.
How often do frontline managers actually give coaching feedback?
Estimates conflict, partly because they measure different things: self-reported hours, share of time, or coaching quality. Read them as ranges, not a single benchmark.
Best available evidence
- Highspot’s 2025 vendor survey (n=350) reports managers spend about 13 hours a week coaching reps.Highspot, 2025 · Vendor survey · n=350 GTM professionals, 21 countries
- Alexander Group benchmarks show first-line sales managers spending an average of 16% of their time coaching, against a best practice of 28%.Alexander Group, n.d. · Independent research-firm survey · Alexander Group benchmark database; sample size not stated
- Objective Management Group data on 9,000 sales managers found only 10% are good at coaching. Over half of the weak coaches, who make up 63% of managers, spend no more than 10% of their time on it.Objective Management Group data (Kurlan & Associates), 2018 · Independent research-firm survey · Most recent 9,000 sales managers assessed by OMG
How to measure this in your team: Count documented coaching interactions (call reviews, 1:1s with feedback) per rep per month. Report the median and the share of reps with none.
Does coaching frequency correlate with rep improvement and win rate?
The best evidence concerns coaching approach and quality, not frequency alone. Structured, ongoing (“dynamic”) coaching is associated with markedly higher win rates. These are correlations from surveys and case studies.
Best available evidence
- CSO Insights (2019, 900+ participants) reported win rates on forecast deals of 41.8% with random coaching, 47.8% with informal, 48.9% with formal and 55.2% with dynamic coaching.CSO Insights (Miller Heiman Group, now part of Korn Ferry), 2019 · Independent research-firm survey · 900+ participants worldwide
- CEB research (2012) found effective coaching could lift overall sales team success by up to 19%, and reps with top-rated coaches performed 8% better against goal.CEB (Brent Adamson, Sales Executive Council), 2012 · Analyst research · Sample size not stated in the post
- Single-customer case study (Seismic): Expedia teams that piloted its coaching approach saw a 13% increase in opportunity win rates. No pilot length is given.Seismic, n.d. · Single-customer case study · One customer’s coaching pilot; duration not stated
How to measure this in your team: Correlate documented coaching interactions per rep with change in practice scores and win rate over two quarters.
How much do managers disagree with each other scoring the same call?
No reliable published benchmark exists as of October 2026.
No published study measures manager-to-manager agreement on sales-call scores. Decades of performance-rating research show that rater effects are large, which is why calibration matters.
Proxy evidence
- In two samples of managers (n=2,350 and n=2,142), each rated by seven people, idiosyncratic rater effects explained 62% and 53% of rating variance. Actual performance explained 21% and 25%.Scullen, Mount & Goff, Journal of Applied Psychology 85(6), 2000 · Peer-reviewed academic study · Two samples of managers (n=2,350 and n=2,142), each rated by seven raters
How to measure this in your team: Have two or more managers score the same 20 calls on one rubric. Report inter-rater agreement, for example as weighted kappa, before and after calibration.
How many reps can one manager coach effectively before quality drops?
Typical spans are published, but no study identifies the point where coaching quality drops.
Best available evidence
- Alexander Group benchmarks put the average first-line sales manager at 8.5 direct reports, with a range of 2 to 38. Inside sales models support 20–80% more reps per manager than field models.Alexander Group, n.d. · Independent research-firm survey · Alexander Group benchmark database; sample size not stated
- The Bridge Group’s 2025 SDR study reports 6.4 SDRs per leader, down from 8 in 2021–2023.The Bridge Group, 2025 · Independent research-firm survey · n=351 B2B companies
How to measure this in your team: Plot coaching interactions per rep, and rep improvement, against manager span. Look for the span where both start to fall.
Does the practice mix (objections vs discovery vs demo) match where deals are actually lost?
No reliable published benchmark exists as of October 2026.
No published data compares practice mix with loss reasons. Win-loss research suggests where practice should focus.
Proxy evidence
- In Klue’s 3,400+ win-loss interviews, product and sales-experience issues came before price as loss reasons.Klue (Adam McQueen), 2024 · Vendor platform data · 3,400+ buyer win-loss interviews, mostly late-stage deals
How to measure this in your team: Compare each skill area’s share of practice time with its share of coded loss reasons over the same quarter.

Methodology
Each question comes from Revspire’s list of buyer questions that lack a data-backed public answer. For each one, we searched for published evidence in October 2026 and opened every source cited here. We preferred primary research from analysts, research firms, academic studies and large vendor datasets that state a sample size and method.
Every figure keeps its original wording, date and sample. Vendor numbers are labelled by evidence type (vendor survey, vendor platform data, sponsored study or single-customer case study). Case studies describe one company and are not benchmarks. Where we found nothing reliable, we say so and show proxy evidence from adjacent fields, clearly marked.
Revspire has not published benchmark data, and no figure on this page comes from Revspire customers or the Revspire platform.
How evidence strength is graded
- Strong
- Independent or peer-reviewed research with a disclosed method that answers the question directly.
- Moderate
- Disclosed-method analyst, research-firm or large vendor dataset that answers the question directly but has limits (vendor-run, self-reported, or partial scope).
- Weak
- Indirect proxy, undisclosed sample, single-customer case study, or a figure more than ten years old.
- None
- No published evidence found.
Frequently asked questions
How often should sales managers coach?
There is no agreed benchmark. Highspot’s 2025 survey reports about 13 hours a week, while Alexander Group benchmarks show managers spending 16% of their time coaching against a 28% best practice. The research suggests quality and structure matter more than raw hours.
Does sales coaching improve win rates?
The evidence is correlational but consistent. CSO Insights (2019) found 55.2% win rates on forecast deals with dynamic coaching, against 41.8% with random coaching.
What is the ideal talk-to-listen ratio?
Gong’s analysis of 25,537 calls recorded in 2016 found 43:57, with the rep talking 43% of the time, and noted most reps talk for 65–75% of the call.
Related on Revspire
Revspire AI Sales Training & Coaching scores role-plays against a consistent rubric and shows managers where each rep needs reinforcement. That makes calibration and coaching cadence measurable.
