  1. Well I think this one is the best metric, for determining how good I am. Because
  2. most people, when I tell them that I'm rated 1800, they don't really know what
  3. that means. Because we don't know the scale, what's the lowest rating and what's
  4. the highest rating, how many people are rated about 1800, how many people are
  5. rated 1,000? This number alone doesn't give us much information. Same with this
  6. number. We know that approximately 8,000 people are probably better than me but
  7. how many people even play chess? However, the percentage tells us a lot. And
  8. that's why the shape of a distribution is even more important than simply
  9. figuring out whether the mean, median or mode are the best metrics.
