| Capability score | % hitting quota | Win rate vs team avg | Deal size vs team avg |
|---|---|---|---|
| 75+ (top tier) | 81% | +20% | +18% |
| 65–75 (above average) | 47% | −3% | −2% |
| 55–65 (below average) | 23% | −6% | −3% |
| Under 55 (bottom tier) | 13% | −11% | −20% |
The middle tier is the largest revenue lever, not the bottom tier. The jump from 55–65 to 65–75 moves quota attainment from 23% to 47% — a 24-point swing across what is usually the largest population in the team. An 8-point win rate gap across 100 opportunities is the difference between 30 and 22 closed deals per rep per year. Multiply by team size.
