I mentioned a couple of times before that accuracy has never been a
design criterion.  Please also keep in mind that there are areas in
the code where we block interrupts, and we make zero efforts to detect
or compensate for this in the timer code.  This simply is not
important.  We are not talking about ppm here, we are talking about
somting that is just good enough for what it is being used, and that
allows easily for +/- 10% tolerances.

Best regards,
