First of all, thanks for taking your time to do this.
A first precision, TWF seems to be ahead of THF but this is because you don't account for cleaves and cleave style abilities. Adding those will, I think, change the picture.
This is relevant for SWF because in the event that those could be used together, say by a fighter, taking Cleaves and SWF would make it come ahead of TWF by a larger margin.
As for SWF vs THF, this of course would not apply, since in principle both styles would benefit equally. It is interesting to see that it would be superior to THF, the reason being the superior attack speed more than compensating for the initial larger dices of the THF weapons.
PS Cleaves can also be used against single target, I am curious, why did you exclude them?
