Here are the auto assign settings:

Here are the group settings for one of the groups in question:

And finally . . . here are the rather bizarre results (just from today for example):

So, six people in the group, and their ticket count:

Brian - 4

Andrew - 2

Joe - 3

Mark - 3

Daniel - 1

Michael - 1

Consider further that two of the tickets assigned to Mark *were not* initially assigned to Mark.  One was assigned to Brian, another to Andrew, but because they are being handled in a special way for us, we re-assigned them to Mark.  So effectively, the distribution as the server determined it was 5, 3, 3, 1, 1, 1.

How does that even approach being considered "round robin"?  I do not understand.  This seems very broken.  To me, round robin means that Brian gets a ticket, then Daniel gets a ticket, then Mark gets a ticket, then Michael, then Andrew, then Joe and then repeat ad nauseum.

Help.
