Didn't Get Pass Time BETA Pin?

I played in at least two beta sessions, one at the very start and one toward the end of the cycle and didn't recieve a pin.What were the criteria?In case it means anything, here's a screenshot from one of the earlier passes, as proof: http://images.akamai.steamusercontent.com/ugc/1465147418245882093/15CB5171E7898F8A04C19C136B4C5191B67FD960/ Dunno if I have any of the later sessions.
