Or if you dont have a vacuum gauge, you could always pull the vacuum line off the regulator while its idling cold to confirm your base pressure. Then while idling hot, pull the line off again and see what the gauge claims your base pressure is when hot. This would subtract the variable of a difference in engine vacuum when cold/hot.
