I'm not disputing this.
What I'm stipulating is that its
gamey, nongranular nonsense (the kind of gamey, nongranular nonsense that you decry in other situations). And that your response to
@Minigiant of "that sounds roughly as sensible than 4e's int making you better at dodging blows" is the exact same sort of nonsensical statement that would lead someone (you in this case) to compare Roger Penrose capability in physics and mathematics to Muhammed Ali's executive brain function where his prefrontal cortex regulates the dynamics of perception, orientation and computing of spatial relationships including relative velocities and angles of intercept, and action are the biggest part of the equation of him being the (possibly) greatest boxer of all time.
Both Penrose and Ali's Int (in D&D parlance) are the overwhelming factors here.
The history of boxing is utterly littered with freakish athletes (omnidirectionally explosive and strong and with stupid punching leverage) who couldn't slip punches and counterpunch. Those guys are relegated to the dustbin of history...forgotten...because at that level of play, what separates the greatest fighters, basketball players, football players, (etc) isn't how physically explosive you are or how agile you are. Everyone is world class explosive and agile. What separates the greats from the JAGs is the speed and accuracy of their neurological loop.
