By my calculations, as of Thursday 8/28 a.m., the current top 24 (all with 527+ pts) have clinched a spot into round 2 (since contrarian23 has opted out).
The 25th entry will be one of:
buddhagamer (522 pts) is done at 522
MDJSupporter (519) can max at 534
bheid408 (511) can max at 526
chargingryno (509) can max at 524
magicdreamer (514) can max at 523
If anybody else opts out, then more than one of the above can advance.
