Hi Jimmy B.,
thanks to a boring teleconference, I have started looking at the screenies... I am not entirely sure but this is what I get out of them:
MC Combat Chip boosted Trabin's skill from 3068 to 3516, so a plus of 448
Knife (Hit) went from 18 +73/96 to 19 + 17/96, so a plus of 0,42
Brawl (Hit) went from 17 + 9/96 to 17 + 60/96, so a plus of 0,54
Whip (Hit) went from 18 +60/96 to 19 + 8/96, so a plus of 0,54
Knife (Hit): 0,42*10000/448 = 9,3% (9%?)
Brawl/Whip (Hit): 0,54*10000/448 = 12% each
So I get 9/12/12 (Knife/Whip/Brawl) while the chipping thread has listed 16/17/12 -- could you verify these specifically? I had to redo them twice, so I am not really sure if this is correct

.
Now I got to pay attention again they are approaching my topics, so talk later...
