The equation above is only an approximation, I'm still trying to come up with appropriate values for some of the terms for the eqs in the paper to derive a better solution. As an example, I have completely ignored any belt creep effect due to the platter itself, which is bound to mean that the real value is greater than my approximation.

As you can see from my response to your near namesake above, with reaonable values of moment of inertia for the platter the response time to these speed variations is in the seconds, so I'm not sure how much variation due to modulation drag would actually be detectable.
