#4 − A Caching Mess

marco (updated by marco)

I recently bombed a local descent right near my house and thought I’d done quite well. Strava told me I’d gotten my third-best time, which is correct by their calculations, as I’d tied my second-best time, as shown below.

 My Results

However, if I switch to the “I’m Following” list, I see my PR as the fourth-best time in the list, a full 10 seconds slower than my real PR.

 I'm Following

On the left-hand side, Strava is showing my time for the current ride, which is four seconds faster than the PR it’s showing on the right-hand side.

I just see these things because I’m an engineer and am sensitive to odd numbers (which usually indicate a bug in software I’ve written). It may be that Strava’s confused because I only show numbers to users that follow me (rather than to all users) and maybe their caching is not optimized for this situation. This happens a lot, though.
