Have you seen telltale parallel scratches on an erratic? I don't remember any but there's this TV show on showing exactly that, I'm thinking the boulder he's showing is not really an erratic

No need to bother... we guarantee that they don't have any 'paralell' scratches. Check for non-divergent ones instead.

Plus you would probably have to turn them over to see any non-convergent lines causing an even longer delay.
