Simply by looking in YOUR petri-dish. If there are just 30 - 80 (if at all) failed grafts in 1 separate section marked with a cross, star or smiley, then you'll know that 30-80 regrown extraction sites, which are spread all over the whole donor area, will be regrowth sites of failed extractions. These can be sometimes the first regrowth sites to see, sometimes they are equally fast with all the other extraction sites.
You'll find such petri-dish photos in this thread.
