If you do it before 15 minute then curation reward is 0. 16 to 29 minute 50% curation. 30 on 100% but there can be a few other weird rules like the amount of folks that already voted...
@kryptik did a nice question piece but I think this way is the best option. Just wish there was more about it in the signup email. Sorry for clippy -- on phone half asleep.
So there is more incentive to vote later?
Kind of, but if you pay attention, you learn that if are not one of the first 50 to 100 votes, then that later incentive goes away...
