The way I understand it is that SRA (stylus rake angle) is the paramount parameter to be set & VTA is a means to that end i.e. you set SRA by setting VTA. Every record is slightly diff. in thickness so SRA set for 1 LP is not going to be the same as another. 2 very similar thickness LPs will probably share the same VTA setting as the SRA for both of them is practically the same.
So, I am not surprised that you arrived at this conclusion that each LP has "only one magic point". It appears to make sense (& seems rather cumbersome to do :-) unless you have a JMW arm, as you do).
FWIW. IMHO.
