I'm autistically watching through the anime and trying to keep track of what level all of Ash's Pokemon should be. I was inspired by the GameTheory video on Ash's Pikachu, so I decided to do the same for all of his Pokemon.

It's been straightforward so far. Just using the average level of Ash's opponents to work out EXP for each KO.

I'm stuck on the Princess Festival episode. There are a bunch of off-screen battles we don't see, but should still count. What is the best way to get an estimate for these off-screen opponents?
