a few points * that does not look like a best fit line, more like a curve * maybe the curve should slope up more at the end? * if the curve slopes up more at the end, maybe as you spend more you reach an asymptote. it would make sense if being the best at something requires more than a linear energy increase than being 2nd or 3rd best at something. * doesn't John Nash's work explain this?
