Enchanting potions don't work

So I have 78 fortify enchanting potions in my inventory. 72 of those increase it by 10% so theoretically i should be able to make my enchantments 720% better right, nope. I'm trying to make my character very op but whenever I try to get a fortify smithing perk on my armour it only goes up to 30% better (keep in mind my enchantment lvl is 100 so its usually at 25%) even with 72 enchanting potions that all increase enchanting by 10% each, and 1 more thing I have 2 store bought potions that also increase enchanting but its by around 20% each. When I use both of those my enchantment goes up from 25% to 30%. Thanks Bethesda. #fucklogic

I play on xbox 1 BTW
