ranges are in constant flux and evolution. i think you're looking at it too complicatedly and just getting too deep.

this is the purpose of balancing ranges in a nutshell...

when we balance, our opposition loses no matter what adaptation they make. this is so because our bluffs are protected by our thin values. if they call us less then we bluff more, if they call us more then they're paying our thin values off with their 'bluff catchers' more. we profit more no matter what their response. when villain does same to us the battle then becomes about who can read ranges the best
