Click on the link for "Schedules" above and use the cyclic versions. Play the matches in order for round 1, then do round2 and so on. This way I think the gaps between to matches for the same team will be as even as possible. If you did this using some of the field balanced schedules from the Excel spreadsheet then you could find some much large gaps or even two matches in succession for the same team which you would probably want to avoid.
