As I say, I understand the goal of having a
cheat sheet that can distills a big chunk of math. But that distillation would have been better done by a neural network instead of the creation of a prompt (fine-tuning or pure distillation). But studying that neural network will be harder.
It's explicitly stated that the goal is to improve performance of cheap models but I assume, like you did, that they are hopping that the plain text may be useful to humans too.
