Replying to Re-mounting touring bindings

Hey guys, so a couple months back i snagged a pair of atomic automatic 109s with trackers for stupid cheap from ebay($160). Anyway, they're mounted at recommended which isn't the end of the world but having always skied closer to centre ( was on bacons at -2.5cm of centre) i'm a little worried that i'm going to feel too far back.

when i ski pow i tend to enjoy finding things to jump off and enjoy throwing the odd three or flat 3 in, i don't want the skis to feel cumbersome and as if the swing weight is completely off.

So i know with standard alpine bindings the general rule of thumb is +/- 2cm of the original mounting point and the skis should be ok, does the same rule apply for AT bindings? if say i wanted to go forward 2 or 3 cm would this create a problem?
