Dear Uru, I am not the font of all knowledge on this subject, hardly. But what you suggest does seem logical; the speed of a tt may deliberately be set to slightly fast with no load, so that it then achieves perfect speed with the load of stylus drag. But in principle, I would prefer a motor or drive system that is robust enough to maintain proper speed under all conditions, because the load of stylus drag is varying all the time due to the groove modulations and also in relation to the distance of the stylus tip from the spindle. It would therefore be impossible to know in advance and for all LPs "how fast" is fast enough to result in correct speed in the presence of stylus drag. So, IMO, this is where torque, the compliance of the drive system, the speed corrective capacity of the drive electronics, etc, come into play.
