This reminds me of previous work showing where you should aim in darts (<a href="https://www.stat.cmu.edu/~ryantibs/darts/" rel="nofollow">https://www.stat.cmu.edu/~ryantibs/darts/</a>). Basically, if you're very accurate you should aim at the 20, but next to it are 1 and 5, so if you're less accurate there are more forgiving spots on the board.
