New Piece Value Formula

1 point per reachable square + one point per supporting piece - 1 point per defending piece. Thoughts?

Isn't that just a reformulation of 'space points'? How many points you attack with your pieces on the opponents side of the board? If you count them up as a tally, say white has 10 space points and black has one, it would be easy to see black being in deep doo doo. And of course double trouble if the space points coincide on one opponent square, say f7 or some such.

is this how computers assign values?

Simplistic. A white knight on e6, supported by one pawn, is rarely worth the same as that same knight on c3 supported by its queen.

Then again, it's not significantly more simplistic than any other common piece value formula.

That formula could fluctuate wildly from move to move as line-moving pieces get blocked and unblocked.

Don't see the point personally.
There's too many variables particularly in an end game.
What "value" would you assign to a pawn one square away from queening?
