The last set of schedules you made for me was so great and exactly what I needed.  I was hoping you could help me again?  A schedule of 2 v 2 with each player playing with all other players in the group once.  This time I have 47 players playing on 6 courts and my second group is 35 players playing on 6 courts.  Thank you so much for being so very kind and helpful!!

Hello again.  I am assuming that you are still want to play about 30 rounds.  In which case 35 players works reasonablly well as you can see below, however I have no way of making the 47 player schedule unless you want 47 rounds.  If there are to be about 30 rounds then the number of players would need to change to 45,48 or 49.  Let me know if you want to see one of those.
