Did anyone managed to get variance, or lap delta, into an usable channel?
There are 2 existing channels for "
session elapsed time" and "
lap start elapsed time"
I subtracted one from another to create the "
lap time" channel that is my momentary time anywhere on track.
I can even use and overlay lap to check for delta, and it matches with motec own "variance" F3 tool, as shown below:
Now with this channel working, I should be able to use the "variance_time(x)" function to compare the elapsed time between my main and overlay selected lap, as described in the funcion info:
so a math channel called "
delta" as
variance_time
('lap time')
should in theory give me the delta between two selected laps, in a way that I could use it as color in the track map for example, or inject into other maths.
But this is not working, the resulting channel is just an empty fixed value.
Can't find my error on the formulas, I appreciate if anyone can help me with this.
