How the numbers work
Two measures, built on every ball of men's T20 cricket since 2005.
Ratings, −5 to 15
- Each innings and spell is rated against all top-level performances on a bell curve. 5 is the middle; 15 is the top 0.1%.
- Batters are compared with others in the same batting position; strike rate against par matters as much as runs.
- Bowlers are judged on economy first, then on whose wicket they took and when.
- A player's rating blends the last 30 months: the last year counts in full, the year before three quarters, the six months before that half.
- Opposition and league strength count. International cricket between the top sides weighs most, then the IPL.
Points, up to 200 a match
- One point is worth about one average run. A run is worth more when the game is tight and the pitch is slow, and less once the result is settled.
- Batting: runs, plus how far ahead of or behind par the batter scored, minus the cost of getting out.
- Bowling: runs saved against par, plus wickets. A top-order batter early on is worth the most.
- Fielding: catches, stumpings and run-outs earn a small share of the wicket.
- Above 150 in one performance, the rest counts half, and no performance can score more than 200.
