Do not reduce Speed Factor by magic weapons.
As far as know the enhancement bonus of magic weapons (e.g., +1, +2, ...etc) affects not only THAC0 and damage but also Speed Factor.
I actually don't like this because this makes Speed Factor less attractive and less ponderable thing while choosing weapons.
Dagger has to have the lowest Speed Factor, i.e., the fastest weapon, as the trade-off of its the lowest damage, and so on.
