A best-of-3 match between amateurs takes eight to twelve minutes, including setting up and
entering the result. Call it ten. The sum is then: number of matches divided by number of
boards, times ten minutes.
16 players, 3 boards
Three groups (5, 5, 6) give 35 group matches. Six go through, with two byes: six knockout
matches including the third-place play-off. That is 41 matches, 14 per board, about
2 hours 20 plus half an hour for the start and the presentation.
23 players, 4 boards
Four groups (5, 6, 6, 6) give 55 group matches and 8 knockout matches. That is 63 matches,
16 per board, about 2 hours 40. This is exactly
Open Darts, and the size that runs best.
32 players, 4 boards
Six groups give 70 group matches and twelve qualifiers in a bracket of sixteen: 12 matches.
That is 82, 21 per board, about 3.5 hours. On six boards it is 2 hours 20 and fits an
evening comfortably.
