Seeds and byes
A draw takes from 3 entries to 64. It is padded up to the next power of two, so 11 entries make a draw of 16 with 5 byes.
Seed 1 goes at the top and seed 2 at the bottom, with every pair after that split between the halves so seeds meet as late as the draw allows. Byes go to the seeds first and then spread evenly through the rest. Both of those follow the LTA’s Competition Regulations, which is what most clubs’ own rules pages are a paraphrase of.
How many seeds a draw carries is capped: two up to 8 entries, four up to 16, eight up to 32, and 16 above that. You do not have to seed at all: leave them blank and every line is drawn by lot.
Third place
Tick Play off for third place and the two beaten semi-finalists get a match of their own. It appears in the draw beside the final as soon as both semi-finals are decided, and it is scored like any other match.
You cannot switch it off once it has been played. Clear that score first.
Playing it
Players enter their own scores exactly as they do in a box, and their opponent confirms. The winner appears in the next round on their own.
Nothing above the first round is stored. The bracket is worked out from the scores every time the page is read. So correcting a score corrects the draw, and there is no second copy of the bracket to disagree with the results. The one thing you cannot do is change a result after that winner has played their next match. It tells you which match is in the way, and you clear that one first.
A knockout match will not take “we ran out of court time”. It has to send somebody through, so record a retirement or finish it. A group match can be unfinished, because a group is a box.
Put a score in wrong? Open the match and press Clear result. It goes back to unplayed and whoever it sent through comes out of the next round. If that winner has already played again, it says which match to clear first, and you work down from the top.
