GROUND the distributor end of the coil wire, otherwise coil voltage goes sky-high and the coil windings (and their insulation) are in danger.

I just turn the fast idle cam to the fastest-idle step. The engine isn't even turning 200 rpm, it doesn't need the throttle wide-open to supply enough air.

Very important. Listen to the cranking speed--the last cylinder should be sounding just like the first cylinder.

I crank until the needle quits going up. Typically 5--6 pumps.

And don't forget to verify the accuracy of your compression tester now and then. If the gauge isn't accurate or repeatable, you need a new gauge.
