Dover:
My reference to it being "a big deal" with unipivots was really with respect to the importance of measuring VTF directly at record height with that type of arm.
Very easy to be out/light .2 to .3 grams if measuring above record height with unipivots. With other arms, not so much of an issue.
I wasn't suggesting in the least that records would be played at that level due to warps or any other reason (ie. installing an aftermarket mat without adjusting for SRA/VTA) that would result in the overhang being off.
