What difference in idle RPM do people typically see between a hot and cold engine? Is 200+ RPM typical?

My IO-360 is about 150-200 rpm.

100-150 depending on the OAT. High time Lycoming O-320 cable driven tach.

For those out there with injected engines....what do you have min RPM set to at cold (or hot)?

Cold is not that much different than hot, around 700 rpm with mixture extremely lean on the ground, very smooth. IO-320
