I think this is mostly superstition and luck. When I hit 939, my strategy was always box 3 first, and then box 2 if I got 2 donuts or box 1 otherwise. This worked almost perfectly for well over a week. I was considering posting like you, and then it just stopped, and I was getting 1 donut non stop!
I think the game is pretty well randomized here and we've likely all tried out various tactics.
The odds of getting 1 donut on the first box you click is 1/3 and every strategy I've tried, in the long run, works out to this.
Thanks for sharing in any case. If you are right or your strategy keeps giving you a better average, awesome! ... I'm permanently stuck on box 3 first thanks to my early experience.
