Equipment above theoretical max?

Um........ Well, I could give you a bunch of screen shots on the items used to forge them, but you may not understand Japanese. lol

Let's say you forge a 34 attack Scarab. You add in a Forging Stimulator, which bumps it up to 39 attack. Then you add in a +3 attack High-Grade Diamond. Then you add in a High Grade Dark Crystal, which works like a Chaos scroll, so that's +5 more possible attack. That right there is +13 attack above average.

+23 attack garnier...
If only maker included 50- weapons.
