This post is to validate the verification comment in BGwiki on Torcleaver at 3kfTP. Currently BGwiki is at 9.7656(2500/256) but the JP forum posts/comments from where this was derived seem to suggest it could also be 9.75 and there hasn't been any exhaustive testing since.
I went to a low level area and did about 200 Torcleavers at 3k fTP as 99DRK with 6% WSDB Job Points. I went mostly gearless to limit the damage range so I wouldn't need so many hits to see the full range. My STR was 100 and attack was 940+ fighting Ogrefly in Litelor which easily cap pDIF and fSTR. I only adjusted the 3K fTP and WSDB values as these are the ones most likely to be unconfirmed.
Actual Torcleaver Range: 3731 -3915
***4.931% spread which is 1 damage away from the full 5% spread.
Conclusion : fTP = 9.75( See very last set of equations). Also, this suggests WSDB from DRK JP points may not be x256 or x1024 based which seems to be the common way many JP forum posters handle variables applied after the 1.05 randomizer in the damage equations.
Dmg Equation variables
Ophidian Sword = 1 Base dmg
fSTR = 8
WSC = floor(96*.08) = 76
pDIF (capped) = 4.25 for Great Sword
fTP values
2500/256 = 9.765625
2496/256 = 9.75
2493/256 = 9.73828125
WSDB Values
106/100 = 1.06
271/256 = 1.05859375
1085/1024 = 1.0595703125
9.765625 fTP with 1.06 WSDB
#1 MIN = floor(floor(floor(floor((1+8+76)*9.765625)*4.25)*1)*1.06) = 3738
