> Simple math for a logarithmic progression, such as varroa increase.  It takes more than 4 (but less than 5) 50% kills to equal one 95% kill.  I will be elaborating on this in an upcoming article.

Well, I dropped out of algebra class in 1967, but does your formula include growth rate? Because if the population increased by 10% between applications, it would require _one more dose_ to get to the same level (95% reduction).
