Impressive HP-25 Library

Davidson has shown fantastic programming skills in being able to execute the code for function f(x) twice per iteration.

Not to belittle that gentleman's work but if you're so impressed with "being able to execute the code for function f(x) twice per iteration" on a max. 49-step calc with no subroutine capability, I wonder what would you think of the two HP-25 programs featured in this PDF document:

            Long Live the HP-25

            - the first one is 36-step long, leaves 13 steps to define the function, and evaluates it three times per iteration, with different arguments each time.

            - the second one is 39-step long, leaves 10 steps to define the function, and evaluates it four times per iteration, with different arguments each time.

I think I've told you about them several times in the past but you seem to forget ever mentioning them.
