Strava Voluntarily Drops Lawsuit Against Garmin
Strava’s multifaceted legal (and social media) attack on Garmin was short-lived. Just 21 days after filing the original patent infringement case, alongside a Reddit post from their executive team at...

Apparently Garmin added OAuth2 to their Connect API: New apps can already use it, existing apps can't migrate yet. More info "this fall".
As a developer, this makes me very happy (maybe more than it should, but OAuth1 really is a pain to work with).

You can see exactly where Wightman’s tank emptied, about 5-10 m from the line (by the Honda sign). If you calculate his critical speed and D’ from his outdoor PBs, D’ was gone 6 m before the line.

Intervals.icu uses pretty much the same method to find max efforts. Doesn't do any pre-smoothing of the power data. I never tried smoothing.

So there you have it. This was our proposed solution to interrogate real-world (messy) MMP data, identify maximal values in that data, and use (only) those to derive CP.

@james-spragg.bsky.social Hey James. Is it possible to share the code or detailed explanation of the "shoulder method" in your "An improved methodology..." paper from 2023? I'm considering making a paper playground (paperplayground.app) for it.
There’s very little on the topic of improving parameter estimates from MMP data. In the OmPD paper we illustrated the issue and @james-spragg.bsky.social @peter-leo.bsky.social and Swart offer one option to address it.
