No, it’s a launch group - each launch group (typically 10 sellers) launches in 30-minute increments, chosen randomly (all this is in the OP, plus much more!). I’m strongly considering launching all 15 Newbies in one group, somewhere throughout the day, so when that group launches every buyer on the site knows it’s all Newbies.
