G-Force Analyzer

I just picked up a new deck for my car with this new gizmo on it and was wondering if it's actually somewhat accurate. Does anyone know? I didn't even realize the deck had it, until I was tuning my system and found all kinds of fun menus to play with. Anyone know iff it's worth calibrating?

A friend of mine had a similar gimmick with his kenwood deck in a mazdaspeed protege. They're pretty accurate, but none the less useless, you usually want to keep your eyes on the road when trying to pull a G in a corner.
