Need some advice from the GTP 1350 users

I understand how useful the Graphic Target Profile can be, especially if the target is big and turns out to be a crushed can. But how accurate is it when we get to smaller targets. A smaller target suggest a coin? Will it suggest with any accuracy if the smaller target is a pull tab as opposed to a coin? I've dug far too many of them already with My ace250 and my MXT.

Second question: how useful is this feature when in the Relic Mode?
