Parsed altitude values changed from version 1.1.0 to 1.2.0

[fgebhart]

First of all: Great tool, thanks a lot!

I'm using fitparse extensively in the workoutizer application and wanted to upgrade from v1.1.0 to v1.2.0 in order to resolve some deprecation warnings.

However, some of my tests failed and it seems like that the parsed values of the altitude records changed from one version to the next. Here is an example:

# parsed altitude records to list in v1.1.0
altitudes_v1_1 = [nan, nan, nan, nan, nan, 2487.0, 2487.0, 2485.0, 2484.0, 2483.0, 2482.0, 2485.0, 2485.0, 2485.0, 2486.0, 2486.0, 2486.0, 2486.0, 2486.0, 2486.0, 2486.0, 2486.0, 2486.0, 2486.0,

Is this expected? Do I have to apply some unit conversion? Since I also get negative values I assume I would need to also add an offset.

This looks like a bug. Can you provide a sample file that exhibits this problem please?

[fgebhart]

Sure. I was using this file and read the records with code similar to

for record in self.fit.get_messages():
    self.altitude_list.append(record.get("altitude"))

Let me know if you need more details.
