I haven't been around yesterday, but had a look at your pattern just now.
The 3% for posts in New (I assume, due to the speed with which you give them out you definitely don't read the posts) is certainly an improvement. Still not caring about finding the best (by whatever definition), because that would require investing time, but an improvement nevertheless.
Unfortunately there's still 10 and 20 times bigger ones for some vote traders in between, old habits die hard?
