Calculating varroa mite levels

As a general goal, try to keep the mite level below a 1% infestation of adult bee at any time–
24-hr natural sticky fall—about 10 mites
Ether roll or sugar shake of 300 bees— about 3 mites
10-min sugar dust drop—about 5-10 mites

    Has anyone been recording mite levels based on the sugar shaker methodology above?
    I have just sampled 11 colonies and the mite count on 300 bees ranged from zero to 13.
