Maths based only on valid laps / only on fastest lap

[steven.casaer]

is there a way to make math channels use only the data from the fastest lap in a run? or, only from Valid laps?
I want to get statistical values (e.g. eng temp or tire temp MAX or AVG) of the fastest lap only, which is not necessary the same as the statistical value of that parameter over the whole run.

Have you considered using reports instead of math channels? Reports operate over different ranges, including laps, segments, and corners. The statistics will be performed for all of the entities, and the highest and lowest values will be highlighted. You can get Min / Max / Average, etc.
