Hello, I'm trying to understand what to do with the block effort, because I don't really understand what the value sent by the api meaning. 
I looked into the code and if I understand well it's the SUM(difficulty/network_difficulty) from shares but the value sent cannot be true because I got something like 0.0033236580321025786, what I am supposed to do with that?</div>
