Have the same seat regardless of the table size or site. I don't feel it is any better than any other seat for card distribution. Never ran into not getting get two cards though. Seat is optimal to the prompts to act. When multi-tabbling, you know where to look and act with efficiency.
Really don't put any stock in rituals or signs before, during or at the end of a tournament or session. More interested in those factors I can control and to the ease they are done.
