 Maybe this is one area where  some hard data can be had and do some good.
 Anyone with a well enough  instrumented engine can plot the CHT  heating
 and cooling rate of  change at any given time.
 Test for this:
 1: on engine start with a cold  engine.
 2: same but with a fast idle.
 3: going full power for  takeoff.
 4: large power reduction from cruise.
 5:  shutdown.
 
 My bets are on #3 and I suspect this one will make the  others look
 insignificant.
 I for one, would appreciate some  response.
 
 
 
 Mark,
 
 You mean somebody with a JPI could show us a chart like this (demo from a
 JPI ad in AOPA Pilot):
