If you use it three times, then every two teams will have played exactly once. For example with the triple 1, 4, 7, then the first time 1 plays 4, the second time 1 plays 7 and the 3rd time 4 plays 7. For the remaining 6 days you can use it 1.5 more times. The schedule isn't perfectly balanced in terms of the number of times each two teams play. To schedule the fields,
For the remaining 6 days you can schedule the fields similarly, but the number of times on each field might not end up being perfectly balanced. Good luck!
