Bought mine a couple of years back. Same temp points but it is just 2mm on the wheel which is 2yds at the 50-55 end of the range.
I did some tests using a heater tape (astronomical eyepiece dew point compensator ) and cooling using low temps found Up North here in Oxford or the traditional bag of frozen peas placed just behind turret. Fixed distance with scope mounted on a tripod. Very consistent and always 2mm. I still have the heater tape and can use it with a battery but did the expt using a precision constant power supply.
So half what Rob sees on his.

Superb scope.
