🏊♂️ The Mystery of the Shrinking Pool
Thursday, January 16, 2025
There’s an odd glitch with my Apple Watch: anytime I finish a swim interval, it claims there are still two meters left. Then after about five seconds, it realizes I’ve stopped, decides I’ve finished a lap after all, and moves to the next interval.
It isn’t the pool, I’ve tried several different ones. Even stranger, it isn’t accumulating by lap. If I finish a 25m sprint: two meters short. A 500m interval: also two meters short. So, it isn’t caused by misestimating the length of the pool.
Anyway, not a big problem. The only real impact is that my intervals are always slower on the watch than in the actual pool, since several seconds get added to each one. This makes it look like I’m much faster on longer intervals, since the delay has a bigger impact on short swims.
