Interesting, the procedures I've read and follow for compression testing are those provided by the manufacturer of the testing tool and/or service manual -- they suggest to never remove spark plugs when the engine is hot because of potential thread damage to the head -- hence why cold torque specs for spark plugs is only 13 ft/lbs.

Also, if the motor is too hot, it will tend to melt the compression testors rubber seal unless your compression tester doesn't use rubber seals and is of the type that can be torqued down.
