Subject: RE: HR Information from GarminGarmin Training Center and MotionBased don't match up either and Garmin owns MotionBased. They'll probably never match across applications. I have no idea what algorithm the programmers who wrote Garmin Training Center used to do their totals, but there are a number of different ways to go about it.
Still, what you have there looks unusual. I'll take a look at the HR data in the morning. Ours basically takes each rtept data point, grabs the HR, sees which HR zone it's in (based on your BT defined HR Zones) checks the timestamp for the datapoint, and adds the time difference from the previous datapoint to the total for that zone. Differences can come into play when deciding how to handle cases like when the previous data point was in a different HR zone. Do you assume that this whole new data point was in the new zone or do you split it up? There are a number of considerations like that, all of which can lead to differences in the way the data gets totalled.
