Just a headsup to Fitbit users who have set a custom maxHR and are suddenly getting crazy burns. I danced a bit this evening. Nothing extreme, for about 90 minutes. And looked at the fitbit data, and saw 650 calories, and being in the max zone for about half of the session :o

Turns out Fitbit lost my custom maxHR data and is applying 220-age, which doesn't work at all for me as my maxHR is about 35 years younger than this stupid equation :D . The app didn't let me chance this back for some reason, but the website did in the end. Phew.
