Maxing out gear with maxed out smithing, enchanting and alchethe

Excellent build you have, that is my first character as well.

Summons work great (you only summon if someone notices you and you can't fire a shot off before they reach you). I personally felt the bound weapon conjuration perks were a waste. This is even more obvious after you raise enchanting.

I use a Daedric bow (enhanced with smithing), and dual enchants of fiery enchant(soul trap + small fire dmg) and I think paralyze if I recall correctly.

I'd much rather have those 2 perks back that I wasted on the bound weapons. Since the enhanced bound bow is nothing compared to a moderately smithed daedric bow. And then the fiery enchant at 1 second is a perfect enchant. Plus you can add another enchant once you get 100 enchanting(not add after the fact, but make another bow and add both).

I maxed Smithing and Enchanting, and was working on Alchemy. I personally think all my characters will max all 3 of those. Enchanting is nearly game breaking, and smithing makes you create ridiculous damage/armor. Alchemy is arguably as good as smith, but due to enchanting being so much more powerful than either, it doesn't matter as much.

Not to mention that I actually fully regret ALL conjuration perks. I still summon if the enemy(ies) are coming at me, but they are there to distract long enough for a shot, not damage. So having multiple (or more powerful) is a waste.

SOLUTION!!!

I can confirm that I too had this issue on the PS3. No matter what I did I could not get above 22% in my items with same information you have given.

I went into game data on the ps3 menu and deleted the game data and the game update for Skyrim. Launched the game and let it patch and reinstall the game. I then went straight to an enchanting table and with no enchanting gear I could create +25% alchemy gear using Grand Gems alone.... I edited a section on Wiki about bugs and stated that I confirmed a solution to this problem.
