On the Ibanez ZR trem, what is the range of dives and pull ups on a scale of 1-10?

1 being a Bigsby, 10 being an Edge/Edge Pro/OFR/Lo-Pro.

I can pull up about a minor third with mine. I use relatively high guage strings though, so it might be different for everyone else.
Someones knowledge of guitar companies spelling determines what amps you can own. Really smart people can own things like Framus because they sound like they might be spelled with a "y" but they aren't.
How much of a pitch increase is that? Like if I fret 12th frer and pull up, how many frets up would it sound?
3 frets.

Personally with my modded vintage trem (as in settings, no new parts) i can pull up more than that, around 4 semitones :P.

Lets say, I am using .011s tuned to standard, how far can I pull up before any string breaks?

(i use .015s by the way, but yea, how much can I pull up?)
