Nigel I can see where it is surprising to you, not being the traditional approach. It was for me as well until Beeboy01 did an experiment back a couple years ago, all the while keeping us updated of the findings as he went along. Coolbees did a similar experiment reporting his findings here on this very same topic, reporting way back in Reply #13. (I realize there has been a lot of ground covered in this interesting topic). Go back and take a look at his interesting findings.
I tried to find beeboy topic as well and with the intention of posting its reference here for you but so far I have not found it. Good stuff uncovered here by both of our fellow members! I am glad you have joined us here at beemaster as well. Your input is very helpful and appreciated!!!

... Treatment day 1 then wait till day 7 retreat. The problem is Varroa exiting their capped cells between days 2 and 6....
I also do 3-day treatment cycles with OAV, for exactly the reason you state. Only, I usually try to treat 9 times (27 day total).
I did mite counts and sticky board drop counts on every hive during treatment - for 2 years. I collected all the data. Based on that data, I now: treat in August (once yearly) & don't count mites. This is what has worked for me, in my area. My bees don't get a brood break due to winter, but they do have a dearth from August till November.
My average mite drop counts would look like this (counted on the 3rd day after each treatment, just prior to the next treatment):
900
900
900
450
300
300
280
320
18
As you can see, the last 2 or 3 treatments seemed to catch a goodly qty of mites, before the drop counts really fell.
I know they say that OAV "stays effective" for 3 days, but my notes showed very little increase in mite drops after about 30 hours post-treatment. Suggesting to me that efficacy drops off quickly.
My data definitely has proven - to me - that a 7-day OAV treatment cycle would not work. Fwiw.
