Each user's number of "votes" in the last two criteria will be limited to floor(earned_merit / (10 or 250, depending on the criteria)).
So for example, someone with 518 earned merits could cast up to 2 votes in the 250-merit criteria and up to 51 votes in the 10-merit criteria, if I'm getting this right.
Someone with 72 earned merits could cast up to 7 votes in the 10-merit criteria and obviously none in the 250.
If I have 20 earned Merit do I vote for only 2 people? And these 2 people will be chosen from my list of 20 people? For example, the first in my list are satoshi and theymos (to determine the order of users in the list I can not). Then they get one vote for 10 Merit and the rest get nothing? Am I right?
