Very true.  I began this as a tabulation of my own treatment, and it grew.  I 
make no pretense of doing Real Science.

Well, I did track the weather, too, and posted it at some points. I may 
add on that data later.  Unfortunately  Environment  Canada seems to update
it sporadically, so daily updates were not practical.  However, they do 
eventually  post it.  My impression was that warm days may have caused the occasional  
anomalous increase in drop, but I did not observe it across all hives on those days.
There are other things going on.  Dee has speculated about some of them.
Personally, I don't know.

From  what  I saw, the weather did have some effect, but not all that drastic.  
Cold days seems to reduce the drop slightly, along with the amount of debris,
but not by much.  Warm days upped the drop a bit, but not drastically.

I treated on some of the colder days, actually, but not below freezing.

No worries.  I appreciate all comments and even kidding can carry  some truth.

For that matter, I have expressed some concerns that we cannot even  compare  the 
two methods I used except by using deductive reasoning and extrapolation.

Even though my efforts are less than ideal, I figure I am in good company in that 
regard when I look at some of the other stuff that gets published.  Additionally,
I hope my feeble attempt inspires someone to do better.  For some reason, no one
seems to have gone to the bother of illustrating this aspect of varroa observation 
on the 'net, although I am sure that many capable  people  have done the work,
then buried the work somewhere.

As Mickey Mouse as my report is, I think it is better than many, and that is 
a shame.
