Yes, Wellington, that is pretty much what I am saying: if a TT have heavy enough platter and the bearing done right then the any speed deviations of motor of belt are kind of irrelevant. I remember years back a Russian guy presented heavy mathematics to model TT interfaces. It was hard belt, loos belt, idle wheel, direct drive. He was trying to prove from mathematical model perspective that one interface is better than another. Interesting that all his calculations according to him make any sense only in context of TT with platters mass comparable to the driving force. He insisted that if platter mass and the consequential moment of inertia is too large then there is negligible difference how the platter is driven. I do not insist that he is right but to me his theory completely makes sense.
