You don't say which figure is what.

Note that calibrate_delay() is itself inaccurate - the loops_per_jiffy
is the number of loops which can be executed between two timer ticks
_minus_ the time to process the timer interrupt itself.  So, it's
actually always a little less than the theoretical number of loops
within that time period.
