When i sync my Blaze to the app it does not accurately report the data. For example when i finished excercising today the report on my Blaze said my max HR was 149 but after syncing, the app showed 145.
Yesterday the Blaze said 143 but after syncing, the app showed 136.
Why does it change the data ?.

Best AnswerTech support tell me this is a 'known issue' and they are working on it but have no idea when it will be resolved.
This is an important metric for me - without it, it devalues the use of the watch.
I will be returning it - which is a shame as in every other way it is a great piece of kit.
