Hi Eric, thanks for the comment.

I see your point, and I admit that I took for granted Fitbit data validity, but I am aware that a proper and lower-level analysis of all the collected data would have been a good first step to take. Unfortunately I just relied on my only wearable device, and started playing directly with the data.

I also just saw about your company, and seems you already have a lot of expertise in the field.. feel I need to read and know more ;D
