Are you SERIOUS? The platter has sagged? Please!

Merely another claim, and no less an extraordinary one at that.
Dick, there are claims and there are claims. Your claims are just
claims too. The thing is, Trevor's claims are based on observation.
And you can't start beating the bias effects or psychoacoustics drum
here. It's simple geometry. It would be pretty hard to mistakenly
diagnose a sagging platter three times if one is even remotely careful
in their observations. You have offered nothing to disprove Trevor's
observations other than icredulity. You will have to do better than
that if you want your claims to be accepted over Trevor's.
Here is a link to another person making the same claim.
