I'm setting up a weekly golf league with 10 players.  We have two tee times each week which allow 8 players to play each week and two players will have byes.  The league will last 30 weeks.  I'd like for each player to have the same number of byes.  Does anyone know the best way to set this up?

Here's one way to play the 1st 15 weeks.  All pairs of players are together within a foursome exactly 4 times, and each player has one bye in each of the three 5 week blocks.  There is a small issue with the same three players together in consecutive weeks in the 1st block.  

    Time 1         Time 2      Bye
( 1  6  4 10)  ( 5  8  7  2)  (3  9)
( 2  7  5  6)  ( 1  9  8  3)  (4 10)
( 3  8  1  7)  ( 2 10  9  4)  (5  6)
( 4  9  2  8)  ( 3  6 10  5)  (1  7)
( 5 10  3  9)  ( 4  7  6  1)  (2  8)

( 6  8  3  9)  ( 2  1 10  5)  (4  7)
( 7  9  4 10)  ( 3  2  6  1)  (5  8)
( 8 10  5  6)  ( 4  3  7  2)  (1  9)
( 9  6  1  7)  ( 5  4  8  3)  (2 10)
(10  7  2  8)  ( 1  5  9  4)  (3  6)

( 1  3 10  2)  ( 6  9  5  7)  (4  8)
( 2  4  6  3)  ( 7 10  1  8)  (5  9)
( 3  5  7  4)  ( 8  6  2  9)  (1 10)
( 4  1  8  5)  ( 9  7  3 10)  (2  6)
( 5  2  9  1)  (10  8  4  6)  (3  7)


For the last 15 weeks, use the same schedule, with a different assignment of player names to the numbers 1 to 10.

Thanks.  This is just what I was looking for.  Much appreciated.
