How exact is the rotation speed of a floppy drive?

Will the start point drift when I turn the index off and the rpm is inexact? If the drift is 1 mS per turn the result will have an overlap of 1mS for each track or worse, lack 1 mS each turn unless triggered by an index. This will also make it difficult to stitch the flux data into real sectors of course.

I can see that reading a DOS floppy with different options, eg ibm360, ibm720 and ibm1440, causes different track time generated which is strange I think.
