It's usually 3 match-ups, then a 24 hour voting period. Once that finishes the next 3 match-ups start, and another 24 hour voting period begins.
Might be an idea to start your match-ups/voting a certain time so it's always consistent?
If they're 24 hour matches, then yes. 3 first day, the other 3 once the first batch ends.
I think 10 AM PST (11 AM MST) is a good time to start each one.
