SG, if you're using the same powder, the same amount of powder, and the wad is seated against the powder, then you have the same area for initial gas expansion. I don't care if you put a 5 inch wad in front of it, it makes no difference. The wad weighing a little more figures in the formula along with the shot when calculating recoil but that's about it.
