The Research on Sales Practice

Stat 1

75%

of sales training is forgotten within 6 days without reinforcement.

Source: Hermann Ebbinghaus's memory research, originally published in 1885 (Über das Gedächtnis / Memory: A Contribution to Experimental Psychology). The “forgetting curve” — the rate at which newly learned information decays without reinforcement — has been replicated extensively in modern cognitive psychology, most recently by Murre & Dros (2015), who reproduced Ebbinghaus's original findings with a contemporary participant pool.

Why we cite it: Sales training relies on memory under pressure. Without spaced repetition or active practice, the curriculum is gone within a week. The implication is not that training is useless — it's that training without practice is.

Stat 2

9.4 mo

average ramp time for a new sales rep.

Source: The Bridge Group's annual SaaS AE Metrics & Compensation Report, which surveys hundreds of B2B sales organizations on rep metrics including ramp time. The 9.4-month figure reflects the median across reported organizations; numbers vary materially by deal size and segment (SMB ramp is shorter, enterprise is longer). The Bridge Group publishes the report annually, so the precise number shifts year to year — but the order of magnitude has been stable for a decade.

Why we cite it: Most reps spend the equivalent of three full fiscal quarters underperforming while they learn. Compressing that window has direct revenue implications. AI practice can shorten the curve because it removes the bottleneck of real-prospect access for new hires.

Stat 3

<6 min

per week — the average rep's structured practice time.

Source: Frank Cespedes, Harvard Business School professor and author of Aligning Strategy and Sales, has written and spoken extensively about the chronic underinvestment in actual practice time across sales organizations. The specific magnitude varies by study, but research on time use in sales consistently shows that structured, deliberate practice occupies a small fraction of a rep's week — often a single-digit number of minutes — while the bulk of training time goes to content consumption (videos, decks, certifications) rather than live practice with feedback.

Why we cite it: Sales is one of the only high-stakes performance professions where practitioners spend almost no time practicing. Athletes practice more than they perform. Musicians do the same. Sales reps invert that ratio.

Stat 4

2x

faster skill acquisition when practice is paired with feedback.

Source: K. Anders Ericsson's research on deliberate practice, summarized in his book Peak (with Robert Pool, 2016). Ericsson's decades of work, originally in chess and music expertise and later extended to sports, surgery, and other domains, established that practice with immediate, specific feedback compounds faster than unguided practice. Related research in the Bjork lab at UCLA on “desirable difficulties” and retrieval practice supports the same conclusion from a cognitive-psychology angle. The 2x framing is conservative — domain- specific studies often show larger effects.

Why we cite it: The argument for real-time coaching during practice isn't marketing — it's a settled finding in learning science. Feedback after the fact is useful. Feedback during the moment is more useful by a wide margin, because the rep can correct in the moment they made the mistake.
