It'd be nice if those of us who are serious about phonographic disk and

which a disk or cylinder turns.  Speed (velocity) is distance divided by
time. (i.e. miles per hour, inches per second)  "RPM" is not a speed.

While I do not disagree with your plea, let me point out that angular velocity is also a "speed" and is measure in degrees, radians or revolutions per unit time. Thus, RPM is a proper measure of angular velocity. Whether it is one we should use in this forum is not for me to determine.
