I found my Cranking Cylinder Pressure (CCP) problem

What we know is you can test 3 different compression gauges on the same engine with the same (hopefully) test method and get 3 different readings. Check, double check and verify.

I did use the same method, WOT all plugs out. I even had a battery charger on just so I would not lose any cranking rpm
