Nah, it's not. I've been following these for quite some time now. I'm not fully certain they're fully daily, but they are consistent. On the days of Monday-Friday when they do occur, they appear at 12:31, 13:01, 13:31, 14:01, 14:31, and 15:01 UTC/WET. None of them ever appear on a Saturday. On Sundays, they're at 11:41, 12:11, 12:41, 14:41, and 16:41 UTC/WET. They always appear 5 minutes before their start time, with a max capacity of 80, Starting Stack of 2000, 6 seats guaranteed, and 2-minute blind levels. There could be more than these, but these are the ones I've tracked in the past. This is for the Titans ones.
