You don’t join a main bracket until you select an end time. The amount of people in your bracket should be in a red band above the black band that states how much time is left in the event. It is easiest to just check the last post in the thread, to see what the latest info someone has provided. If the time zone settings in your user profile are correct, you should be able view the time the person posted, to see how current their info is. There is a possibility of multiple brackets filling side by side, so join a “fresh” bracket at your own risk.
Useful info to provide
1)Time slice you are in
2)Current amount of people in bracket
3)Leader in bracket with amount of points
4)Time you joined the event, if it was not right before posting in the thread.
Time slice - _______
Current bracket - _______ people
Leader - _______ (name) / _______ points
Always include slice information with your updates. It’s unreasonable to expect everyone to jump through all of the previous posts to figure out which one you’re talking about.
