I'm sure many of you like to look and analyze your stats in Garmin connect after an activity.
Garmin already provides plenty of graphs and values but there are still many of useful stats that you can extract from an activity.
There are some very nice connect iq data fields that do record extra graphs and fields in the fit file, but all of them are limited due to memory consumption since the extra fields and graphs are not their main purpose. Some of these CIQ data fields are: cardio Drift, Dozen Run, Fat Burner, etc.
The main purpose of the data field i'm suggesting is to only write extra fields/graphs to the fit file, and no extra memory would be used to present the data while running.
Also with custom calculated data fields the possibilities could be endless. (like the AppBuilder datafield does it)
Some of these extra data fields can be:
Energy Expenditure
Running Economy
Cardio Drift
VO2 max
Steps
Carbs Burned
Fat Burned
GPS Signal strength
etc.
