Again, you will be reading the engines oil temperature, not the cylinders head temperature. The engine could be overheating before the oil reaches x temperature, depending on the airframe.
It could be simplyfied on the game, but not on the logic afore mentioned.
They coud make as a common assumption for the overheat to happen always at the same position of the needle, but change the times it takes to reach there on different airframes.
On reality, with the same engine, and different airframes, you should have different critical readings.
Reality will be reasonably well represented, simming won't.

You need to make a decision about the level you want to push realism to. To completely monitor an engine, CHT is not enough. You need EGT (exhaust gas temperature) also. Then you need to factor low quality instruments typical of the era. Then again you need to consider that liquid cooled engines have less temperature difference between cylinders, while air cooled engines often have a critical cylinder, not to mention their vulnerability to cooling shock. The list could go on. I think that once the time-to-overheat and time-to-cool off is correctly modelled, realism is acceptable.
In my opinion, of course.
