To use seafoam or water, you just start up the engine and hook up a vacuum hose to a nipple on the UIM, drop the hose in the Seafoam or water container, hold rpm at 3000, and let the engine vacuum suck it in.
Apex seals aren't the only seals in the engine...you could have a bad side seal, corner seal, flattened apex seal, corner seal, or side seal springs, etc. Most of these failures will drop compression on a single face, whereas apex seal damage will drop compression on at least two faces.
That's why you use the piston tester, remove the Schrader valve and watch for even consistent bounces. Don't pay attention to overall compression numbers.
I did pull the schrader out, the bounces were 75ish 50 50. Two faces were noticably lower then the one, the front was like 55ish 30 30 again two were very noticably lower
