I seem to remember the rule being all cylinders within 10% of each other and everything is cool. As others have implied, valves & rings have a good bit to do with what compression you achieve. In my testing, I made sure that all cylinders had spark plugs out except the hole being tested, that the ignition was well grounded to avoid being zapped, and that a good "cumulative" type tested was used, which capture the max reading until you release them. I would never try the old timey hold-it-against-the-plug-hole type, too much variation in taking readings. The type which thread into the plug hole with Oring seal are much better.
Lastly, take a set of readings and then you can optionally do the "add a teaspoon of oil to each cylinder" test, which should raise your readings I think if your rings are going away. A valve seat problem will not improve with the oil test.
Good luck.
