Of course, as with everything, it's limited by the quality of the data, so if you see things (and there are a bunch) that don't make sense, remember that they might be wrong! Especially for the less common training types, some of the effects (especially the estimates of how height affects training speed) could be quite far off, but for many of them, I think we're pretty close.
You have enough data now, I believe, that you can publish static results once a month or season and that shoudl be nough for people. It is cool to see all the most up-to-date data fed and analyzed and all that...but its causing trouble.
It worked fine for me in Chrome this morning. Two things you can try:(1) In the Extensions page for chrome, remove the old greasemonkey script before installing the new one.(2) Clear cookies.If it's still not working, can you give me a bit more information about what's going wrong?
