Hello Ian,
thank you for your reply. I was not specific enough and your answer is the correct one if we play one round per night.
Have a look at the jpg attached. You will see two blocks of 8 teams playing. Note how one playing night (red box) consists of three rounds (opponents).
The problem is that e.g. team 16 has to drive from one location to another, which is what I like to avoid. This is happens for most teams.
If you have suggestions regarding how to keep all teams in one location per night and play three rounds, that would be wonderful.
Thank you in advance, and for this great site.
best wishes,
Marcel
