I broke all my workout records sitting for 8 hours in a bus with the Galaxy Watch

Bumpy bus ride (last seat) over eight hours.

40 floors climbed with 11000 steps. Anybody else have had this issue when in a vehicle.

Just wondering if other brand watches also have this issue or galaxy watch overestimate stuff. Ironically when I actually climb stairs it tends to under report by 15%

I am on latest software update which came out a week ago
