So presumably if you set up the SRA to 92 degrees on a medium thickness record(140gm) then playing a ticker or thiner record will not affect the SRA that much? Obviously if you record collection is predominantly 180gm records you would set up for that possibly.
Some years ago, Roy Gandy of Rega, wrote a technical paper about adjusting arm height and it's effects. It's all rather technical but it turns out that to do the job properly, the arm bearings would need to be something like 9 inches below the record surface, which is of course, impossible. His findings are that when we faff about with height, we are polishing a turd so no need to lose any sleep over it. It's on the www somewhere.
