Very trivial question, but if anyone would happen to know the answer to this, it would be nicely appreciated.

Does anyone know how many trades are required to max out Ryu Book III in .hack//Quarantine? I've done over 1000 and it's still going. I've maxed out the other 7, it's just this one that I haven't totally taken care of yet.

I'm trying to finish things up in Quarantine so I can get to my second playing of G.U.: Rebirth (so I can toast it this time instead of stumble my way through), then onto the other G.U. games. It's just this Ryu Book and the Item Completion quest that are in the way (and Item Completion is no issue).
