How it works
Stats
Pick a fighter, choose Stats, and trust your numbers. The faster and cleaner you solve, the harder you hit — from gentle early grades all the way to Olympic-level challenges.
The mean is the everyday "average" — it's what each one would be if you shared everything out equally.
For 4, 8, 6: add them (4 + 8 + 6 = 18), then divide by how many there are (3) → 6. Total up the list, divide by the count.
Type the average.
