Well, here are the "surprizing" results for the HP-32s, optimized by placing subroutines W and Z at the beginning of code.
Factoring 99,999,989 (a prime number)
Old method, using numeric constants 2, 1, 4, and 6: 144 seconds
New method, assigning 2, 1, 4, and 6 to variables A, B, C, and D (outside the loops) and RCL them: 146 seconds
So this would indicate the 32s does not seem to suffer from this malady.
