I saw this so maybe it will help- https://www.youtube.com/watch?v=5eszFbLtKx4
Also the use of some thin felt or similar between the clamp and the record label to reduce wear and scuffing.
Thanks for the feedback. I will try something in between the clamp and label. I have watched the video and I appreciate it. It's hard to know if I'm "over tightening" because you do want the record flat to the resin platter. I just know now when I use the clamp, it leaves a "ring" on all my labels and I'm not happy with that.
It's an actually indentation. Can't necessarily feel it but you can see it. Does your friend have the Acutus ? The acutus clamp is different than the clamp for all the other tables, but not sure that even matters. I may be tightening too much , but Avid did say that over time the label would be marked by the clamp and to try using a piece of thin paper as a cover .
I know this post is old, but I thought I'd add to it anyway, in case it helps anyone else. I emailed Conrad Mas directly about this issue. He said to use a thin piece of felt, cut to fit the Acutus clamp (looks like a donut). I have been using this tweak for years. It doesn't negatively affect the sound and leaves no marks on the label. You can clamp the record down as tight as you want.
