Do you still use stand-alone ("pocket") calculators?

My FX-991ES does it in 2m56s - I must have an overachiever (or different ROM). My older FX-991W (c2000) does it in 1m28s, but rounds the result up to 718.

It may well be a different ROM. In this little devices I believe that there will not be differences in hardware, like different revision boards or something. My lack of speed or accuracy, starting and stopping the stopwatch, would not justify 19s of difference between our results.

My HP 48G+ finished it, took a long time (sorry, didn't measure it), but it arrived to a result of 717.928325369.

Thanks for your information. Can you please describe how are your FLAGs configured (list of the active ones). I might have a FLAG wrongly configured in order to my HP48G be able to solve the problem.

EDIT: info on HP48G FLAGs

Was a long time Casio FX5500 user. After discoverying Hiper Calc Pro for android, I have retired my 30 year old Casio FX5500 and never looked back.

I'm still learning and discovering what features hipercalc has, but being able to type the equation exactly "as it is", just like an academic paper written in LaTeX,  is a very big plus and is enough for me to ditch everything else.

My flags are all cleared. My calculator has been recently reset - funny story - I harvested the SRAM from it to upgrade a TDS2CM (TDS200 series oscilloscope expansion module) to a TDS2MM, then replaced it with a slower SRAM. Doesn't make a difference for the HP48G+, but could make a difference for the TDS2MM. So yeah, that means my calculator was reset, so all flags are set to their default value, that is, they're cleared.

I have an Casio FX-991MS and also use Speedcrunch.
Speedcrunch is a nice command line-ish calculator.

If you press shift-7-on (together), 9, then press shift 5 times, you get the rev. and ROM checksum.

Turns out this one is my fx-991ES PLUS (I do have a non-plus model around here somewhere). GY455X VerE, SUM 8928.
