Thread the gap: precision Bump'n'Runs to a tight pin

Put 36 golf balls into 3 groups of 12 balls. Spread the groups around the green between 1 and 10 yards from the edge and 5 to 30 yards from the hole.

Mark 3 landing zones in a straight line at the edge of the green, each 6 feet (2 meters) apart.

Hit 36 bump-and-run shots: 12 to zone 1, 12 to zone 2, 12 to zone

Use the first set of 12 balls for zone 1, the second set for zone 2, and the last set for zone

Keep ball positions and distances the same for the whole test.

Put 3 markers at the edge of the green, 6 feet apart, to make 3 landing zones in a row.

Hit 36 bump-and-run shots: 12 shots at each landing zone.

Switch between ball lines. For each zone, hit 3 shots from one line, then 3 shots from the other, until all 12 shots per zone are done.

Each time a ball stops in the right zone, count it as a successful shot.

After all 36 shots, add up your successful shots and enter your score in the app out of 36 attempts.

Place 10 piles of balls in two lines that cross like a plus sign. Each line has 5 piles, 3 yards/meters apart.

The piles should be 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole.

Mark 9 stop zones on the green in a 3x3 grid, spaced to cover different parts.

Hit 36 bump-and-run shots, divided into 9 groups of 4 shots.

For each group, pick a stop zone and hit 4 shots from any piles.

A shot is successful if it stops in the target stop zone.

Repeat until 4 shots have been aimed at each stop zone.

Count how many shots stopped inside their target zones. Enter your total out of 36 attempts.

Arrange 40 balls into 10 piles with 4 balls in each pile. Set the piles in two lines that cross each other near the green. The two lines should be 6 yards apart. Each pile in a line is 2 yards from the next pile.

Pick 3 target flags on the green. Space the targets 6 feet apart in a line or triangle so each one can be aimed at.

Hit 36 bump-and-run shots, in 3 sets of 12 shots. For each set, aim all 12 shots at one of the target flags (Zone 1, Zone 2, Zone 3).

Start at any pile and try to hit the ball so it lands inside a 10-foot circle around the chosen target. Do this for 12 shots, then move to the next target and do it again, until all 36 shots are done.

Use different piles as you like for variety, but always set up the same way for each shot.

Count each shot that stops inside the 10-foot circle as a success.

After all shots, count total successes and enter score in the app, out of 36 attempts.

Put 2 rows of 20 golf balls each on flat grass near the green, 5 yards apart.

Make sure both rows are between 5 and 30 yards from the hole, and keep all balls on the fairway, not on the green.

Split the 36 shots into 3 groups of

First 12 shots, try to land the ball within 5 feet left of the hole.

Next 12 shots, try to land the ball within 5 feet right of the hole.

Last 12 shots, aim to land the ball in a 5-foot circle around the hole.

Hit every third ball from each row: start with one row (balls 1, 4, 7, etc.), then switch to the other row, and keep going until all 36 shots are done.

Count each ball that stops in the right target area as a success for that group.

When all 36 tries are finished, add the successful shots and enter your score in the app, out of 36.
