Thanks for the explanation. One suggestion/advice is to vote after 15min to "maximize" your curation reward. Since a comment doesn't get many votes usually, after 15 min would be optimal in most cases. If this helps or not, send me some DRAMA :)

It does vote after 15... I guess you are going to have to be more dramatic.
in my case, voting came less than 3 mins usually. This time as well.
