Thread the needle: roll your Bump'n'Run to tap-in range

Set up two lines of balls next to the green on a slope. Each line has 18 balls, 5 yards apart, between 5 and 30 yards from the hole.

One line has balls above foot level, the other line has balls below foot level.

There are two groups: 18 shots from balls above feet, and 18 shots from balls below feet.

For each group, hit every third ball in the line until you hit all

Aim each shot to land and stop in a target zone on the green, 5 to 10 yards from the hole.

First, hit all 18 balls from above feet, then all 18 from below feet.

Count each ball that stops in the target zone as a success.

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

Set up two lines of balls (18 balls in each line) next to the green on sloped rough. One line is above feet level and one is below feet level.

Set each line 5 yards apart. Balls should be between 5 and 30 yards from the hole.

Hit 18 bump-and-run shots from the above feet line and 18 from the below feet line (36 total shots).

For each line, hit every third ball (leave two balls between each shot). Finish all shots in one line, then switch to the other.

Try to land and stop the ball inside a 6-foot circle around the hole.

Count a success for every ball that stays inside the target circle.

Add up all your shots that stopped inside the target circle, then enter your total score out of 36 shots in the app.

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.

Count each ball that stops inside the target zone as a success.

Add your total successful shots and enter your score in the app out of 36 attempts.

Put two rows of 18 balls each on grass near the green. Keep the rows 5 yards apart.

Put both rows about 10 yards from the hole.

Make three target zones on the green: Left, Center, and Right. Each is about 4 feet wide.

There will be 36 bump-and-run shots: 12 for each zone.

From the first row, hit every third ball to the Left zone (12 shots).

From the second row, hit every third ball to the Center zone (12 shots).

Go back to the first row. Hit every third ball to the Right zone (12 shots).

Count the shots that stop inside the target zone.

Add 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.

Set up two lines of 18 golf balls each on a sloped fairway near the green: one line on the uphill slope, one line on the downhill slope. Balls should be spaced 5 yards apart, between 5 and 30 yards from the hole.

Place 3 target zones on the green in a row, 6 feet apart. Call them Zone 1 (closest), Zone 2 (middle), and Zone 3 (farthest).

Hit 36 total bump-and-run shots: 18 from the uphill line, 18 from the downhill line.

From the uphill line, hit 6 shots to each zone (6 to Zone 1, 6 to Zone 2, 6 to Zone 3). Always hit every third ball, skipping two balls between shots.

For the downhill line, repeat the process: 6 shots to each zone, using every third ball.

Count a success each time a ball stops inside the intended target zone.

When all 36 shots are done, record how many balls landed in the correct zone, out of 36 attempts, in the app.
