Dear @thuchan : With all respect and only trying to help you as I said you are a follower and geometry alignment is not rocket science. It’s extremely simple.
Because is plain geometry/mathematics any one can manipulates numbers and achieve a different alignment.
That’s what Stevenson did it and that’s what the SAT tonearm did it too.
It’s a way to achieve a perfect alignment? NO it can’t do it and those mathemathics explain you why you can’t do it.
Stereo or Mono the main issue does not changes because exist a length in the LP surface, exist the recorded LP area, exist a begin of the recorded grooves ( this is the most out side groove. ), exist too a end recorded groove ( most inner groove ), exist the pivoted tonearm,etc, etc
Al those does not changes and it does not matters what you want to do you must take in count that most inner/outer grooves distances to make your calculations ( stereo or not. ). Maybe you can ake other " road " but at the end:
the main subject for the alignment calculations ( any kind. ) in any pivoted tonearm is to obtain the overhang and off-set angle to mount in accurated way the cartridge to the tonearm and the tonearm in the TT.
From where do you think comes the null points? do you know which is the use of those null points? do you know from where comes the tracking distortion numbers over the LP recorded surface? why exist the inner/outer most grooves different standards as: IEC, DIN or JIS that achieve different calculations alignment parameters values?
Do it a favor and find out by your self the rigth answers to those questions with out ask any one and you can be sure that when you achieve the rigth answers then you already understand in deep the alignment subject.
That’s all and till today you still just can’t understand it ( because I think that you not even intented to do it. ) and if you follow been a " follower " ( yes I know that him told you discovered the " black thread ".) you will live your audio life deseiving in this specific subject. Is up to you.
Regards and enjoy the MUSIC NOT DISTORTIONS,

that is a confirmation that even that chart/diagram in the link you can follow it to take in count why you are wrong with your kind of statements..
