It's interesting that the 35s is faster doing register arithmetic
(STO + Z) than simply +ing on the stack. Is that because dropping
the stack each time uses more steps? regards, Glenn

Maybe it is due to the different types that might be on the stack. Is it a real? Is it a complex number? Each + might require that to be checked, whereas a STO+ operation might not. Guessing.

I think everyone tries to forget that unit for a variety of reasons. . . :-D

What about in integers?
#1 << DO #1 + UNTIL 0. END >>
My 49 died a while back :-(
So did my 48sx :-(
And no batteries for my 28s and a broken battery door to boot :-(

For my 50g, I get 19692 (average of 3 runs).

Hello Gene,
congrats, a real great compilation of that simple benchmark across several generations of calculators!
However, for the great HP41C/CV/CX one benchmark is missing: MCODE
In the book "HP41 MCODE for Beginners" of Ken Emery, published 1985, a 20-step machine code for this 1+ addition algorithm is presented (pages 50-52) which I wont list here.
To make things short:
Count: ~130 000
This is about 100-fold of FOCAL or Synthetic programs!
The 41 was, is and remains amazing
