However it is clear that the regulator output quickly rose just off of idle and maxed out @2200 RPM. With the engine speed above 2200 I operated high beams, 4-way flashers and brake lights. Voltage dipped somewhat (I didn't write down the value) but alternator output was a CONSTANT 22A.

Remember all of my measurements at the fuse block include 55W additonal load of the dual headlight mod even at low beam. And, I stayed low with my estimate of available wattage because of variations due to heat, battery health, manufacturing tolerances and contact between terminals at various points. As they say, YMMV!

If needed I could make another load test at the fuse block to get current readings with different loads. However I don't believe that the regulator output needs to be retraced as it has a definitive peak.

BTW, thanks to all for the kind words. I try to give back some of what I have teaken from this board.

We all try to learn from each other. Thanks for sharing your knowledge, time and effort.
