John Schmidt dedicated a lot of time and effort to his attempts and that is what it takes. It's not that high runs like this are necessarily out of the Reach of the likes of Orcollo, it's just that it will take time, probably a lot more than he is willing to put in. Also there is the knowledge needed, which of course can be gained, but takes time..There is also the Luck factor, which will probably stop many, otherwise good attempts. A lot of Things has to go right for this to be pulled off.
I've heard cocky snooker players, especially, talk about how they could run 200 balls in straight pool without any difficulty at all. Then they run 60 and miss and think that proves their point...Why are People so God damned stupid? Most top elite players today are probably well capable of 200+ ball runs. But 400 or 600? Maybe not, at least not easily, and not just any pro. It takes a special kind of personality to stick With it, and to play the game correctly, without slacking off. Dennis has the raw ability, but does he have the stamina and drive to do it? I doubt it. Once he gets his first skid on a 200+ run, we'll se what he's made of. I've been wrong before, but I'm not holding my breath on this one. There certainly is easier Money to be made for Dennis.
