RE: Calculator benchmark
I found a way to spare keystrokes on HP-15C:

HP-15C

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  **ENTER** g x²  **+**  RCL 1  **g** 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 40 keystrokes.

TABLE ENTRY and RESULTS Display: X and Y displayed after each press of A or B key.
Code:
**2.56  B    3.12  A  **                            // [←]  2.56  B                   Eventual press [←] to clear ERROR 0 when non initialized register R1 (B value) is zero   10                1.28  B                                                                    5                .64  B                                                                    4 6.24  A                                                                                  5 2  RCL*0  A                             (12.48=2* 6.24)                                  5 2  RCL*0  A    .32  B                   (24.96=2*12.48)                                  8                .16  B                                                                    4               1.32  B                                                                    5 18.59  A                                                                                 6 17.63  A                                                                                 6               2.64  B                                                                    5               5.28  B                                                                    5
Total 69 keystrokes for table entry and individual X and Y result display. if the user is not concentrate enough to read the X value during the pause, one additional press on the [X<>Y] key may exchange X and Y on display.

Score : 109
In case of a full functional and awake user !

**EDIT: keystrokes count and summation corrected
