The rules a golf pool needs before the first tee time: picks, the lock, changes, withdrawals, missed cuts, ties and payouts. Each one shows how pools commonly handle it and exactly what TourneyRun does.
Not on your own. On TourneyRun picks lock early Thursday morning at the course, before the first group tees off. In an Office Pool the commissioner can still swap a golfer for another in the same tier, so agree in advance on when that is allowed.
If he drops out of the field before the lock, he disappears from the pick sheet, but your pick stays until you change it. Swap him before the lock. A golfer who never tees off gets no penalty rounds and no automatic replacement, so your team plays one golfer short. In TourneyRun Style, if the scoreboard still lists him as withdrawn, he can take the missed-cut points deduction.
He is scored like a missed cut: the rounds he did not finish are filled in by the pool's missed-cut rule, the fixed penalty of 8 over par per round by default.
In an Office Pool each entry predicts the winning score to par, anywhere from -30 to +10. When two teams have the same score, the prediction closest to the winner's actual score wins the tie. Over or under does not matter: a guess one stroke high beats a guess two strokes low.
They share the place, shown as T2 or similar, and TourneyRun does not split the prize between them. Settle the split in your rules before the tournament. Adding up the prizes for the tied places and dividing evenly is a common approach.
TourneyRun does not block picks for unpaid members; the commissioner marks each entry paid. Many pools make payment by the lock a written rule, and TourneyRun emails unpaid members who have picked within 24 hours of the lock when there is a buy-in.
In an Office Pool the missed-cut rule is locked once the tournament starts. Other settings, such as the number of dropped scores and the payout split, can still be edited, so state in your written rules that nothing changes after the lock.
