the reason for first 3 singles and last 2 or 3 singles is to not have to have all the players there the whole performance. with 3 singles to start the card only need 9 or 10 eearly gamers there by 45 minutes prior to post so the later gamers dont have to show up until game 4 or 5 and no early gamers need to stay until the last few games. simply very helpful for a short roster.
