I kinda understand what he's saying, I did not do the stat your talking about here but I find it odd considering how I will do the stat. IMO a left first/get left on stat should not even include reds, usually the stat guy would use text explaining what rules they created for the stat about to be presented useful.
Sure there can be a stat about how many times a driver goes red, I personally did not look at that. I am sure it's around somewhere but I do not think the sport uses a stat like that. A redlight is something that no driver wants to do and nobody advocates going red, it's also messes up the left first stat. It's a much more useful tool for everyone (fans, racers) to see how many times a driver left first or got left on and defining the parameters of the stat disqualifying bye runs, redlights, and runs where the driver was unable to take the light. Left first should be a simple, direct 1 to 1 stat where any time a racer goes green against another drivers light, that should be the only info ever looked at.
