My guess is that the 25% is applied to the base amount rather then the total %. What I mean by that is that will 100 enchanting skill and no perks the magnitude of potions are double that of their base. So if the potion is @ 16% with 100 skill level, then 8% is the base amount. 25% of 8% is a 2% increase.
Just my guess. If my memory serves me correctly, when I started enchanting at beginning levels, the highest i could fortify a skill with a grand soul was 8%.
