How tight should band be?

[aovakyan]

I was wondering how tight you guys were wearing the band. I've noticed at the gym that if I have it on pretty tight where the band doesn't wiggle at all I get better results for hr then if I have it a couple notches loose. Just curious how you guys have it and if there is any official word from MSFT?

I loosen it when just wearing it around the house to make it comfortable but tighten for exercise. I'm even trialing putting the display out when doing exercise as I think the HR works better when the sensor is under the arm on more visible veins.
