For a while i've have seen something strange on my watch(maybe someothers have this issue): when i climb stairs, the watch does not counting everytime.Today for example this happend to me and then i've take a look to the display watch and check my heart rate, so my heart rate was low beyond what it have to be when you climb stairs.Also i've saw another behaviour when climbing stairs: when i climbed some floors, the watch does not count the floor but when i am starting to take a look into menu of the watch, then it show me the climbed floor.I guess it's something about refreshing display and cpu.Also i think it have something to do with the heart rate value that you have in the moment when you climbed floors/stairs.Anyway, earlier i've climbed 4 floors and the watch did not count any of it.And also for me it appear strange the fact that the heart rate did not go up even if the watch it's tight on my wrist, like always. I am using firmware version 6.75
