i did mine by first checking the SRA angle with the tonearm level,(not really necessary) then setting it a close to possible to 92 degrees,as it happens thats with a slight tail down position.
i used an alignment arc protractor downloaded from the vinyl engine site to align the cartridge,i spent some time getting it dead right here,then lastly small tweaking of the tracking weight.
the hard work pays off when you hit the sweet spot believe me!

all this was over a period of 3 days on and off
