Yes, I didn't get from Bill T's post that he was referencing zero sealed brood.  BTW my numbers show that a 600 mite drop 24hrs after an OVA treatment, where there is still some scattered brood, equals about a 40 count mite wash. I just did one on 7 seams of bees that washed at 40 mites earlier in the month. The 24hr stickyboard drop was 605. The colony was showing stress from varroa.
