Hi, EdS2:

Thanks a lot for posting the information I requested, much appreciated. Having a look at it, I have some comments, read on (my highlighting) ...

That seems to be 104, as seen in post #3 upthread:

SETUP:

Code:

g P/R f CLEAR PRGRM Enter new program 4 f LBL A STO 0 GTO 1 Code to input A and goto display 7 f LBL B STO 1 Code to input B 5 f LBL 1 RCL 0 g x² RCL+0 RCL 1 LN - f PSE Code to display X=A²+A- LN B 16 g LSTx ENTER + Code to display Y= LN B² = 2.LN B 4 g P/R f USER Return to RUN mode and 4 USER mode easiest start of A & B codes
Total of setup is 36 keystrokes.

C.Ret says Total of setup = 36 keystrokes but I count 40, which coincides with the sum of the column at the far right.

The TABLE ENTRY and RESULTS' keystroke count is probably wrong as well, as he says, for instance that the sequence

2 RCL*0 A .32 B (24.96=2*12.48) 8

is 8 keystrokes long while it's actually 9, so the total count for this part might be wrong too.

There's no "fine detail of what should be counted", it must be keystrokes for the HP-15C, and a keystroke has no ambiguity, either you press a key or you don't. Anyway, the point is moot because the 104 count is highly suspect as there are errors in both the Setup and the Computation/Results posted counts.

Also, apart from the wrong count, the Setup part is less than optimal, you can significantly reduce the keystroke count as well, so it's still not clear what the minimum count for the HP-15C would be and if it that would make it the "top" model for this particular benchmark.

Thanks again and best regards.
