What am I looking for with strobe disc?

Hello, I'm a little lost here. A friend lent me a PLC to use with my VPI but I don't really know how to use it or how the strobe disc works. Can somebody shed a little light on this for me. Thanks

When on 33 rpm,the 33 marked portion should be at rest and stable.If it drifts,then an adjustmentment is in order.Provided the table has such a device. Seans' description is right on target.My observations are referenced to the KAB unit.

Is the drag created by the stylus significant? Will it vary from record to record (or even track to track (or even moment to moment as the pitch of the music changes))? Will the drag vary depending on the weight of the platter? Is the industry standard 33 1/3 assuming no stylus drag? Are we all nuts to worry about this?
