AR7 mounting question

[Gr0mo]

I have the 2011 AR& and it has a mark on it that says -5 recommended mounting point. I was under the impression that recommended was -2.5? I don't think anything changed from the 2011 to the 2013 (or even 14?) so why do the 2011's say recommended is -5?

Also anyone know the recommended mounting point for the Libtech NAS freerides? mine has a plate on the top sheet with markings ranging from "sweet spot" to "core center" but I can tell it's not right.

Actually i did some research and it looks like that's recommended for more of an all mountain ski, but for park its -2.5.

Now I'm interested in the Lib tech's. I did some measurements and it looks like the plate on the top sheet is incorrect. Does anyone know where the "sweet spot" is supposed to be in relation to true center?

I'm gonna bump this because I'm about go get my new (2013) ar7s mounted, and I'm wondering how people like it center compared to -1 cm or -2.5 cm.
