Four kicks is what I give them. How the gauge rises tells me as much as how far it rises. When the engine is in good shape usually three kicks does the vast majority of the rise, four is just for good measure.
Gauges and techniques vary so compression numbers are pretty subjective. raw compression numbers alone don't mean all that much to me. At my shop, anything that has the plug(s) out of it gets checked and noted on the work order. That way when it is back in my shop I have a baseline to go against( I deal with a lot of triples-sleds).
My own stuff gets checked a) right after buying new-or rebuilt. b) at regular intervals afterwards.
When I see the numbers falling off it is time to order in refreshing parts. If the run condition goes to hell, again I have a baseline to help my evaluation.
