Changes to fitness & freshness curves?
Today (1/24/2017), I noticed that my "fitness & freshness" curve drastically changed compared to what it looked like yesterday. In particular, when I peaked last year, in September, my fitness index was around 40, as of yesterday. This morning, it shows that I was at 100. I am not sure why old data would change all of a sudden. Was a new version of the site released overnight that would cause this apparent regression?
