Playing the game well enough means A- not B+. I used to think about this in University a lot with the grading system. On the face of it nobody really seems to notice the +/- distinction. There is a more primitive grouping of A/B/C. The difference between being an A grade player and a B grade player is 1 point. If you're 79 points you're B+. If you're 80 points you're A-. But it's a world of difference between being perceived as an A player vs. a B player. By that same token, the effort/reward ratio for striving for A+ is crappy.
