Ive been of the same opinion for years. This whole fargo thing seems to be motivation to try to push me higher. I know several 600-650 players in my area (for 20 years) and have always been a big underdog when gambling with them. I'd always get a good amount of weight.
I don't think hand-eye coordination can be improved significantly. Instead, I think if my patterns get better, that might be the best chance I have at improving overall. My thoughts to improve this are to watch a pro "ghost" set on video, and pause the video after the break. (not watch the rack). Then mark my table the same way. Take BIH and run out. Keep doing this same table layout for several hours, maybe even several days, trying many different paths, until I am convinced I picked the best path. Then watch how the pro did it, and reconcile why he did it that way, and how close it was to mine. I did this a couple years ago with my own random break pattern (not duplicating a pro's), and it was super helpful. I basically taught myself the best pattern for the racks I played. I think comparing it to a pro's pattern would be helpful.
This will be a lot of work. I don't know if I'm willing to do it. That's the truth
