Great to see more people joining in, and glad you're liking it so far. Sorry I haven't had more time lately to add new features, but for those that haven't been checking, the analyses that are already up there have been getting more and more accurate as more data has been added. The training speed section is getting more useful as filtering for certain ages and heights is more likely to produce meaningful amounts of data, and the age effect curve has gotten nicer and nicer (28-29yo is the one area that still looks pretty odd, because we still don't have a ton of data there, so if anyone's training older guys--even by accident!--it'd be great to get your data included).
We should very soon have something up on trainer level. Between busy holidays and some confusing data (the effect of trainer level looks very different for 18-19yo's than 20+, so I'm trying to nail down whether that's just noise or indicative of some underlying design feature) this has been a bit slow to roll out. But we've got good amounts of data, so hopefully we get there in the next week.
As a small update, the usage stats page now lists the top 5 training types this week (see what people are doing on those shortened weeks, or in the playoffs, or just what the latest trends in training are), and all time (hint, everyone loves OD!).
