In May 2019 I removed the log collection feature on zwiftalizer.com. I removed aging features that would have required a lot of maintenance to bring up to date - namely the benchmarks data collection. The main constraint is my limited free time, not hosting costs (but more on that later). My time is dedicated to my family, then career, then fitness. Hobby projects are frozen. It is unlikely that the benchmarks or the power sources reports will ever come back.
