means. One of the reasons I can fly with a 12 lb tail wheel, 150 lbs of
fuel behind the cg, and 125 lbs of cargo back there too.

Too damn hot to think this afternoon. Forgot everything I should have
shared above.
John W kept precise numbers on everything he did, whether it was a local
flight of 10 minutes and a leg of a 60 or 75 hour cross country flight. He
also kept precise numbers of his tests.
During flight testing of maximum and minum forward and aft cgs, John W used
weight in the nose of the aircraft progressively heavier until the airplane
would not leave the ground. He did the same with aft cg by adding weights
progressively, then test flying. He told me when he had gone beyond the aft
cg limit, he did not know it until he stalled the airplane (intentional),
the tail dropped and he could not get out of the stall at idle power. He
had to go full throttle to get enough air flow over the tail to get the
Kolbra flying again... Something folks might remember should they ever find
themselves in a similar situation.
I have never done "ultimate flight testing" with forward and aft cg,
although I thoroughly flight test any time I make a change either way.
