Yes, but in my experience this improvement was aided by a more human tour scheduling. In ADTOE he reached the top of his game in the middle of each leg, after usually a week of warmup, or a little more. After that, a week and a half long plateau and a smooth decline in the last week. This is what happened the last time judging on bootlegs and concert videos.
I think he might be at the top of his game right now, but I also believe that to keep it that way he needs to start decreasing the amount of performances, or keep the gig density at least as low as it was in the immediate past. More or less what Roger Federer is doing right now with his career of tennis player.
