Is it correct to say all data saved using the new functionality to save to FIT files will be saved as a developer data field? So for example muscle oxygen sensors like BSX and Moxy can't use a ConnectIQ app to save the data from the sensors like section 6.3.1 of the "ANT+ Device Profile - Muscle Oxygen"?
Also currently there is no unifying standard to developer data fields so that means there is no easy way for developers to say I'm sorting X data and by X I mean the same data as this other app that stores the same thing. As in the way an Edge 810 and a 920xt both save power meter data to FIT files in the same way so anyone looking at the files doesn't have to care who generated the file but that they want the power data.
