It's interesting that some people are so enthralled with items like the Zone VI compensating timer. Obviously, it does not know what developer is being used, and I assumed it used the Arrhenius Equation (I like to say that as I know how to spell "Arrhenius"...) to make it's time corrections. There's even a newer version of this type of timer being made that is software along with a stand-alone USB temp probe. Kind of funny.
