These attention rates are not easy to understand... How they calculate this metric for every post independently? How can that work? It is probably calculated every day.

Every Scoring Round Snax distributes a limited amount of tokens to the users of supported social media (e.g. Twitter). The amount of tokens, which user will receive, depends on the Attention Rate of their content, and the total Attention Rate of all content published on the social network.
