Given the result seen here, I would suggest a recommendation to drain no more than 2 or 3 frames per day:

I also strongly agree with the idea from @Michael_Bush and @Semaphore that each frame should be opened in ~20% increments, so that the back pressure of honey doesn’t flood the hive.
I would also like to see more emphasis on considering a double or triple brood box, if that is usual in your area. A lot of new beekeepers seem to think that the Flow hive can magically manage with just one box, and I am very fearful that in the northern US, Canada and Europe, that will result in massive colony losses this coming winter. People don’t read enough, but at least if it is in the manual that bees need sufficient winter stores, you have tried to educate them that the hive is a new method for harvesting, but not a new method for beekeeping.
Thanks for your efforts, and thank you for listening to user feedback.
