as was mentioned, it's a better way to calculate % infestation.

(if someone doesn't want to kill bees, powdered sugar can be used instead of alcohol. i choose alcohol so i can have a better comparison to others using alcohol)
what's not clear at this stage of the game is what percent infestation is being tolerated by bees in treatment free operations. i know about my own in the next year or two. in the mean time, i'm hoping i can get some numbers from other treatment free beekeepers. the problem is that many of them don't sample for mites.
beekeeping since june 2010, +/- 20 hives, tf
