I don't know about everyone else, but I was at 86F because I live in Phoenix, AZ, and the air conditioner in our house failed several times this summer, and it took over a month to fix/replace all the relevant parts. The first failure took place when we were out of town, and I probably lost 4 out of 20 eggs because of it. 86F meant that I had a few degrees of wiggle room, and probably saved the rest of the eggs when the air conditioning broke the second time.
