Because statistically speaking it’s not true, and we talked about it in the previous thread How is the Coding Rank calculated?
player count is a matter of sample size on a statistical sample. Having more players in theory won’t move you a lot on your relative position. If I’m in the top 20% for 1000 players, I’ll be in the same 20% with a population of 20000 players (maybe with some confidence error
Sample size is the basics of most statistical analisys and quantitative research. This has a big background on research and real use cases in all fields. It’s not something I made up just for CG rankings.
