Your testing is admirable but the batteries you are testing that use the pb eq ratings, can they replace a 94R battery rated at 725 cranking amps and 85 amp hours. I've been driving around with it in my 1991 Mercedes 420SEL. It will start it at least ten times in a row with the headlights on. The Lightning is rated at 4.6 amp hours. I think that's a good battery stress test.
