Nope, I didn't forget the motor at all.
The motor certainly is not directly connected to the platter, there is a compliant rubber coated wheel between the motor shaft and the platter. Speed and W & F should be in the same area as a belt drive minus the slippage a belt drive can have as it's a simple mechanical reduction between the motor shaft diameter and the platter contact area diameter. Slippage on an idler drive is non existent if it's adjusted correctly. Remember, professional idler drives come up to speed almost instantly. If the ratio's are correct, speed will be correct. Idler drive motor RPM is set by incoming line frequency that is held to a very close tolerance.
If your looking for the ultimate in speed accuracy and low W & F measurements, the better DD will give you that easily.
I have nothing against a well built belt drive table but they have their issues as well.
Your ramblings are so full of inaccuracies it puts your credibility in question.
