When I download my flight logs and use the PhantomHelp log viewer, I add up the total flight time for each date.  I am confused, because for one date, my flight log shows a total of 24323 seconds (I use the Sum function in Excel CSV). That converts to 405 minutes, which converts to 6.75 hours.

That does not compute. I only have 3 batteries, and we all know there is no way you can wring that much flight time out of them.

What am I doing wrong?

TIA,

I use airdata to store my logs and it also calculates the flight time per battery per flight, some really handy info there. Register for the free version and sync your dji log in under settings

Will do, thanks! Got a paper log to start using because if I have to surrender my phone for authorities to see my flight logs, that's my primary phone number and communication device. I'd much rather hand over a paper log.

Thanks for the app information - now for one flight, it's a much more realistic 18 minutes, 26 seconds.
