Autorotation RPM change with temperature

Hello Ladies and Gentlemen,

What is the effect of temperature on Autorotation rpm?, I have consulted various tombs on FPC and from what i can deduce an increase in DA should cause a increase in ARPM.

The reason I ask is the certain type I have the dubious honor to fly (SH2) does not seem to conform to this rule. Despite the test flying schedule clearing saying this should be the case.

If this happened once I could have put it down to not being rigged correctly in the first place, but this seems to happens all the time.

does anyone have any idea why an SH2's auto rpm decreases with a decrease in temperature?

Many thanks
