Sounds interesting and promising but not entirely consistent. Can you really call it a "peak" in grip at about mid life when after that point the grip is maintained constant on a plateau? I would not call that "peak" per se, just a plateau. It also does sounds quite fishy that tread wear decreases but grip stays constant (again after about mid life). Lastly when does the plateau end does it simply hit a vertical "brick wall" right at the wear bar or is it right at cording? It must come down at some point and even get below the grip when just broken in. If it drops in the way he described then it must come down sharply, like going over a cliff.
