A transparent batting impact score that rewards both runs and scoring speed relative to a format's par strike rate. Illustrative composite, not an official metric.
score = runs × (strike rate / par SR) — illustrative blend of volume and tempo

A rough benchmark for normal scoring in a format, around 130 for T20 and lower for one-day or Test cricket. Beating par lifts your impact score; falling short lowers it.
Because 50 off 30 balls is more valuable than 50 off 60 in a run chase. Volume alone misses tempo, which this score tries to capture.
Only loosely, through the par strike rate you choose. A fuller impact metric would weigh the game state, pressure and opposition, which this simplifies.
As a quick comparative read that values aggressive, productive batting, not as an authoritative rating.
