Minor Bug.
I am writing an INTEGER value to the FIT file. On the Web version of Garmin Connect, the Chart properly displays PRECISION = 0 (no decimal point) in both the Y axis and for the value on the graph line. However, in the Garmin Connect Mobile graph, it displays as PRECISION = 1, with a decimal point.
Not a big deal, just inconsistent between the two platforms and the mobile view is not respecting the UI specs.
