I am pretty bad at curating for rewards, but I still do pretty good. I vote when I read or see a post even if it is three days or more old. I do get some lucky timed votes on stuff I read, but not often. Yet I still am in the 9% range of APR, how someone can only be at 2% is just unbelievable unless they are voting on their own comments and not meeting the $0.020 dust vote level.
I have a morning cycle where I vote and get to a 12 hour recharge point, then I do it all again before bed so that when I wake up I am not sitting at 100%
