Can you elaborate on sou's or blocks?
Earth64 is calling units "blocks," and I'm not clear on how he has defined "forces." (https://www.chess.com/forum/view/general/how-to-analyze-position-scientifically-part-1)
Conceptually, I separated location (= squares) from units for the purpose of developing a very general chess notation that described both, although later I found such a notation already exists (called RAN), although I'll still need to modify it extensively. I had a long response written for you here, but since your question got me to rethinking my approach, I think I'll hold off until tomorrow before posting it.
The other thing that has occurred to me is that your concept of a system is static as it relies solely (?) on pattern recognition whereas my system is intended to be more dynamic. For example, I have a notion called string theory to cater for the fact that there are numerous permutations when there is attack and counterattack in a position. I invented the idea to formulate some relatively simple rules to deal with such complexity. The idea was to point the player in the right direction (the "probable" solution) rather than have the player wade through the variations aimlessly. Strong players do this intuitively but they also miss things.
