Every Second or Smart Recording

Many garmin devices (and others) have a setting on the device to tell the machine how frequently to capture data. Typically this is "every second" or "smart" where it will capture data if it senses a change in a field.

Is there any way from the FIT file to determine if they had it set to "every second" or "smart". I couldn't find anything in the docs (but might have overlooked it).

The recording rate is not currently stored in the file. You should be able to calculate it with reasonable certainly by dividing the number of record messages by the moving time in seconds. The results should be close 1.0, but 0.90 to 0.95 might be a safer threshold. Even with one second recording enabled there may be the occasional two second gap between records. Give it a try and let me know how it goes.
