The final day (Sunday) needs 45 match slots for all semifinals and finals but has only 40. Finish nearly all quarterfinals the day before, add courts/hours on the last day, or trim the field.

Court-time capacity

Friday	4	2	20
Saturday	12	8	80

Schedule ~119 of 140 theoretical slots – the held-back capacity absorbs late starts, long matches, and court turnover.

Breakdown by division & bracket

Every division runs one draw per bracket. Filled to 12 players, a single division looks like:

Bracket	Draw size	Matches
Singles	12 players	11
Doubles	6 teams	5
Mixed doubles	6 teams	5

21 matches per division × 5 divisions = 105 total matches.

Suggested day distribution

Day	Suggested use	Target matches
Friday	Opening rounds	20
Saturday	Early rounds & quarterfinals	40
Sunday	Semifinals & finals	45
Total		105

Alternative scenarios

Registration policy	Recommended	Aggressive	Comment
Up to 3 events per player	60	60	Best balance of capacity and schedule reliability.
Up to 2 events per player	80	80	More players, but fewer cross-draw entries per person.
1 event per player	160	160	The most players; each competes in a single draw.
Two-match guarantee / consolation	39	45	Extra matches per player reduce the cap sharply.
Round robin	Well below	Format-dependent	Group size and advancement rules drive the match count.

Final operating recommendation

Cap the field at 60 unique players.

Entry limits: 60 singles entries, 30 doubles teams, 30 mixed doubles teams. Keep a waiting list and expand only once real entries show players entering fewer events.

The real constraint is event entries and player conflicts, not headcount – a smaller field entering everything can be tighter than a larger field entering one event each. Estimates assume single-elimination draws.
