OK.  If we look at it differently, and consider the _area_ under the lines in  
your chart and mine, which represents real total mite death, rather  than 
the _baseline_, which has an indeterminate meaning, then it seems clear
to me that the total  mitefall in the hives under observation here is much
greater than your model predicts.

It was on that that I based my (tentative) conclusion.
