Speed of 41CL vs i41CX cs V41

[Gene]

Here are some numbers using ...

First, the usual speed test :-) is LBL 01 + GTO 01 with the stack containing ones and a zero in X.

Second, here are my results:

i41CX+ in fast mode (iPhone 11) : 3705 counts in a minute.

DM-41X in fast mode (on battery): 12,895 counts in one minute. <-----------

DM-41X in fast mode (on USB): 40,301 counts in one minute. <-------------

Standard HP-41C (from PPC Journal issue where HP-41C was introduced), same program: 1041 counts in a minute.
