I sort of doubt that you will find it to be some nice multiple of the normal
speed.  It's probably just whatever it happens to be.  In other words, I am
not sure the designers didn't just pick a circuit that made it "fast
enough."  Nevertheless, you should be able to figure it out.  If you can
record a tone at a known frequency, play it back with the recorder at the
highest speed possible, and determine the frequency of that tone, it would
then be only a matter of some simple division.  Of course, that assumes that
you have the necessary programs and equipment to do so.
