Punch damage

[akadiablo]

According to wiki,

Punch damage is 50 * sqrt(str / 10).

. With 52 str and knuckles I punch guy without armor and when he is moving, 114 dmg ,without knuckles 92 dmg. Then with 84 str and knuckles to 140 dmg.
Damage without knuckles should be 50*sqrt(5.2)=114, 84*sqrt(8.4)=144. So where are i am wrong?

personal beliefs : full peacefull decreases damage 20%
str 52 punch damage : (50*sqrt(52/10))*0.8=91.2
