On the website it's saying that i have 120 polearm WPF, about 30 of it a bleed off from my 1h WPF
In game however it is reading me at about ~~ 90 polearm WPF and 180 1h WPF (when on the website I have 190 WPF)
I did some tests with another byzantium on the duel server using a skip the fun with true 120 WPF and my main which on the website says it has 120 WPF as well
(same PS, athletics, naked, no shield, same distance, same enemy, same armour, same weapon, always from full hp, same attack direction / speed, no holding attacks)
When i was testing it seemed that my weapon was faster with the STF and it seemed to be doing more damage. I could be wrong ofc, because 30 WPF is quite minor, but we were testing it for quite a while and it seemed rather different having the 30 extra 'real' WPF compared to the 'bleed' WPF.
