My 945 LTE decided not to record any laps in my most recent swim. First swim since a FW update (4.16) and suspect something went wrong there... working that out with the 945 LTE forum and Garmin.
Still, this lead me to editing my Activity on the Garmin Connect Web Site.
Is it just me, or is the math somehow really wrong?
I clicked "edit" for the activity and see I can manually change the Number of Lengths. Initially due to the 945 LTE issue this showed 0, so I edited it and noticed the total distance didn't seem to match the math I would expect.
i.e. 100 laps of a 25 yd pool should be 2500 yds, not 2734 yds, right?

For what it's worth, I think the activity, once the edit is "saved", is correct...
