LOL!
I realize that in most turntables, the speed is well-enough controlled that you don't consciously hear the wow or flutter components of speed controls.
However, it may be registering in your hearing in a way that causes you to think that one turntable "sounds better" than another, for reasons that you have a hard time explaining or describing.
Typically, a person is about 10 times more sensitive to flutter than to wow. So flutter must be kept to a much lower level than wow must be kept, in order for it to not be easily perceived.
This may possibly be why very different turntables with very disparate measurements in the "wow and flutter" category may not sound discernably different, even though one table may measure 10 times less than another. It may depend on what component of speed variation(wow or flutter) is present in their drive control(and at what amounts). A table with primarily flutter in their speed variation must have about 10 times less measured variation, as a table with primarily wow speed variations, for them to "sound about equal".
Maybe not many people really care about this, as long as they sound fine, and that's great.
I'm just pointing out that no turntable system has perfectly controlled speed, and that there are variations which need to be dealt with, and that they may influence what you hear if they get beyond a certain level of perception. Engineers will need to be concerned with these things when they design a turntable, but listeners must only be concerned about what they hear as the result(thankfully!).
It seemed to me that some proponents of the various forms of drive systems wanted to point out some technical aspects of why their "favorite" sounded better, and why their "less favorite" did not sound as good(to them). I thought that some of this technical information may contribute usefully to the discussion.
