Bottomline: Clean out the hole properly and the equilibration rate will be much better.
Of course, a clean hole is a happy hole.
But you could camera up the bottom of a hole drilled in a say 4 " x 2' x 2' slab. I bet if you call up Howard K he might have some laying around. Think utube. You could show us the diff between a dirty hole vs a cleanly scrubbed hole.
