Mafia451 has a "Mafia Academy" where people train to be better at reading. They use the Briar Score to keep track of their reads: https://forum.mafia451.com/t/how-to-measure-your-read-accuracy/4836
I know quite a few people who do this, and some of their scores are pretty impressive. Granted, I have some issues with the way accuracy is measured here, but that is a discussion for another time.
i'm more interested in what the samples are like. Scoring an individual readslist is easy (although i would probably have used a different method) but it won't be outside the range of realistic random variation on its own.
There are two big obvious concern with measuring a mafia players reads. The first would be concretely determinining concretely what a players reads are. Do the players you know who track their scores only evaluate unambiguous readslists or do they also score less ambiguous reads? (ie: maybe they take themselves saying "i don't want to lynch x today" as meaning they read x as town that day.) The second is selection bias. How do they choose which read lists to use when factoring in their career score and additionally how do they choose when to post reads lists?
There are some other factors which could conceivably affect the result to make a person much better at guessing than a random number generator, such as factoring role-info into reads (ie: if a person claims to be a doc and targeted a player and there was no nightkill you'll be reasonable in guessing that player is more likely to be town). This is still probably "reading" but it borders on solving via mechanical info and wouldn't translate into a vanilla game.
