>Pardon my skepticism, but how is this success measured.
No apologies necessary, Pete--I admire skepticism! I measure by the mite
levels of colonies, as determined by alcohol wash. First check is of
potential breeders in March--mite levels have been going down for some
years.
Second is in mite levels in late summer, and what degree of treatment is
required to keep them below 2%.
So, compared to previous years.
>And what is the "normal distribution" to which you refer?
Some colonies keep mites to very low levels, a few colonies suffer from
high levels, although no where near as high as in previous years. What I'm
interested in are the majority (within a standard deviation of the mean).
