Hi Golden,
That particular tournament will continue running until 3:00AM EST on April 25th (Midnight PST). After the tournament concludes will we need to verify the results and then you'll receive your credits. Most tournaments are paid out within a week of the end-date, however there are some instances in larger tournaments where it can take a just a little bit longer.
Congrats on the 7th place so far! Keep in mind that event is an unlimited play tournament which means you can play as many times as you want between now and the 25th to try to improve the score you've already put down. Even if you shoot a higher score, you'll still get to keep your lower score so keep trying to get that first place if you can.
Good Luck =)
*edit* It's the Top 70 players in each tier for any tiered event, yes.
