14 minutes 59 seconds on my HP-42S! The faster running time on the HP-20S can be explained by the higher perfomance index of the latter, according to this benchmark.

The WP 34S version is about only 200 milliseconds slower than the fastest one so far:

Code:


LBL A                         LBL A                   
TICKS                         TICKS
EEX                           EEX
4                             4
ENTER^                        #000
#000                          #001
RCL Y                         +/-
1/x                           RCL/ Z
x<> Y                         STO+ Y
-                             x<> L
DSE Y                         DSE Z
BACK 005                      BACK 005
TICKS                         R^
RCL- T                        TICKS
END                           RCL- Y
                              END


166.2 (avg. of 5 runs)        163.8 (avg. of 5 runs)     

16.6 seconds                  16.4 seconds

Cheers,

Gerson.

Edited to correct an error: 14 minutes 59 seconds, not 14.59 seconds.
