Minimum Number for Swiss Teams
I thought it would have been easy to find the answer to this, but google proved me wrong.
If I'm running a Swiss Teams event with 6 rounds (of say 8 boards), what's the minimum number of teams I need to make it worthwhile? 7 is pointless (might as well run multiple teams), and 8 seems only marginally less so. Even with 10 the principle of Swiss isn't really being seen.
