I wonder if ELO makes sense for something like this that is so inherently unstable/not-normally distributed? I.e., in chess, if you're playing an opponent whose rating is +800, you have less than 1% chance of beating them. But in this case, we have Peppa Pig currently at 1875, vs. the BMW 3 series at 1072. Can we really say with any confidence that Peppa would beat the BMW 99 times out of 100? It seems unlikely that increasing the number of matches will change the instability of this rating.
