This is very useful and thorough, but there's one thing that could use a little clarification:

Currently if you vote as soon as a post comes out you get zero curation rewards, they go 100% to the author.
At the thirty minute mark you get 100% and none go to the author.
In between these two points it is on a scale so at 15 minutes you and the author share 50/50.

I could see this being read as "voting after 30 minutes gives nothing to the author at all," especially considering there was no mention of how posts pay 25% to curators and 75% to authors.

Curation rewards are always 25% of post payout, so voting after 30 minutes simply means you get 100% of that 25%, where voting at 15 minutes would forfeit 50% of that 25% - or 12.5% of your total vote strength (not considering who you voted before or after) - to the author, giving them 87.5% overall. I'm gonna upvote this for visibility.
