The problem I see with this is that it’s not very useful for people to know if something is a +3 or +4.1 position. The qualitative descriptions that underlie that rating is what’s important. How does my pawn structure compare to my opponents? What is the balance of minor pieces (knight and knight vs bishop knight, BB vs KK, etc.)? That’s how you get to understand chess.
Yeah, this is probably better for a game like Go where evaluating raw point differentials is a common thing that professionals (and even strong amateurs) do.
