I think we should switch to an ELO Rating System
Nevermind,
I don't know if that is possible
Many federations and organizations may use the formulas, but their systems will be different due to each system's non-interaction. So a player may have a US Chess correspondence rating of say 1400 and a Red Hot Pawn rating of 1700 because the two systems don't interact/exchange data.
On the other hand, E.L.O. did rock back in the day.😛

the ratings of USCF and other systems correlate nicely. the reason that they may not seem like they do is that at any given time each active players' ratings vary. my rating may be 1600 one day and 1300 on a different day, but my average rating is fairly steady and is quite close to my uscf rating.

The rating system is a statistical performance model - It can only provide a measure within the population that provides the base data.
You can't take a rating from RHP and say it equals or is greater or less than anything other than another RHP rating.
You'd need a large number of people who participate in both systems to be able to start comparing ratings between one system and another - and even then it would be pretty meaningless.
You may find that your ratings go hand in hand - but you can't generalise and hold that as an assertion that holds true for two systems.
