Well, it's true when comparing different machine/language/OS but with the same hardware/software environment the comparison is largely code-independant. That's why the simple-loop test is enough to estimate the relative speed difference.

Quote:RESULTS:
Rev A ROM HP 42S (2934Sxxxxx): 2499.99946106 in 591 seconds.
Rev C ROM HP 42S (3328Sxxxxx): 2499.99946106 in 609 seconds.

The numerical results are identical. The speed result difference is negligible...all that can be concluded is that this particular ROM A machine is 3 percent faster than this particular ROM C machine.

This is another, independent indication that there is no significant speed difference between HP-42S software versions (version A only slightly faster than version C).
