Why not (in a hypothetical rating update; I don’t think this should be changed until then if ever) get rid of the gap by labeling the range [2k, 1d] like so?
- 2k
- 2.0k
- 1.5k
- 1k
- 1.0k
- 0.5k
- 1d
- 0.0d
- 0.5d
Then the numbers have a meaning as distance away from shodan, with dan and kyu marking positive and negative numbers by convention?
