I think in watching Jayson it is clear he wasn't worried about making optimally correct choices.
There is a balancing act between caution and aggression, between strategy and execution. It is clear with this attempt that he believed the key to big runs was to maximize his execution. He did this by putting very little conscious thought or effort into most shots, he played with a breathtakingly quick pace, and he prioritized confidence and rhythm. I would say that his record results have provided strong evidence this is the right approach for a high run attempt, for him if not for everyone.
So when we look back through the run we can all find many examples of decisions that seem ill advised. What we can't lose sight of, however, is the 832 shots he successfully pocketed, some of which he might not have made had he been more deliberate along the way. It reminds me of players watching bullet (60 second time controls) chess and making notes in the comments about how a checkmate was missed when both players were racing along with just seconds on the clock.
In short, the ultimate yardstick of good pool is the results and his results speak for themself. We can look at individual shot selections, moments where he used poor technique, balls that wobbled and didn't strike the center of the pocket, and shots that required him to get a bit fortunate for him to come away unscathed. All true and unavoidable in any long run. In the end, though, the best thing we can do is applaud a new world record and take some notes for our own game.
