This is so cool. Thanks for laying it out so clearly! :-)

I'm particularly interested in the times of day and week to improve the chances of getting attention. Back in the mists of time (pre-smartphones), I read someone recommending posting fic early in the week, when people were at school/work but not super busy yet (because a lot of people only had internet access at school/work then). I've been wondering how that has changed over the years.
