Elo rating software with automatic random matchups This question is not about chess per se, but I am looking for a software that could generate random matchups through a list of 200ish options/people, then I could choose the winner and it would rank the outcomes with Elo rating (or something similar that would also work).

I'm currently using EloRater, but I have to manually generate random numbers from an external source to then create the matchups, scroll down through the list, find them, choose the winner, etc.  I am doing simulations and I need to do many, many matchups from a list. Thus, something that is user-friendly and speeds up the process would greatly help.

I think such software probably exists for chess. Does anyone of anything that could help me?
Dont know elorater but there is likely a way through the opsys to randomly pick (that part is easy) players to match and then insert them automatically into elorater instead of typing them in.  If they have a way to import tournament results you might be able to automate it even easier.  Just create all the random matchups you want and then submit it for rating.
