BAM Cinema - Standby Ticketing Question

Quick question for anyone who's done Standby for a BAM Cinema screening. I wasn't originally free to attend tonight's screening and Q+A of The Witch, but I am now and the showing appears to be sold out. The website says Standby is made available first come, first serve, but I am not able to get there until 30 minutes before the movie starts. Anyone know what my odds are of getting in, if any? I know there's no way of knowing, but just curious before I potentially trek all the way down there.
