Umm, no... from the discussion so far, I'd say that you are the one doing exactly that.

Well, the incline experiment is a real world measure of actual stability. In the absence of a test to, say maybe 100 degrees or so, I'd be inclined to consider the incline experiment as a less certain way of finding LPOS than the longhand method using the full lines plan.... but a far more certain way of determining it than using the "short hand" method based on simple ratios & a fixed input number. I am aware of how incline experiments work. I'm not sure which way is the better to calculate AVS. AFAIK nobody ever said the Tayana had an LPOS of 110 degrees but Evan Gatehouse was pointing out that the mathematical formula used to derive it's claimed LPOS used 110 degrees as a fixed input no matter what the boat or hull type. The original graphs posted by Popeye calculated the AVS at 110. That was the genesis of the discussion. In the above statement, I was pointing out to Mr. Gatehouse that his estimate of the 460 being "tender" based on the LOPS and ballast ratio was not necessarily correct. But he should know, he sails a cat. (No ballast) Before that, he owned & sailed & cruised a real crab crusher. IMHO the gentleman knows that of which he speaks. What's a crab crusher?
