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

Get 36 golf balls and split into 2 groups of 18 balls each.

Put one group of 18 balls on the uphill slope, close to the green.

Put the second group of 18 balls on the downhill slope, about 5 yards from the green.

On the green, set up 3 target zones in a line, about 6 feet apart.

From the uphill pile, hit 6 shots at each target zone (first at Zone 1, then Zone 2, then Zone 3).

From the downhill pile, hit 6 shots at each zone in the same order.

Ball counts as a success if it stays in the chosen target zone.

Count how many shots landed in the target zones out of 36, and enter the score in the app.

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.

Set up two rows of 20 golf balls each, 5 yards apart, on sloped rough near the green. One row is on uphill, one on downhill. Place rows 5–30 yards from the hole.

Take 36 shots total: 18 from uphill row, 18 from downhill row.

On the uphill row, hit every third ball until you take 18 shots.

On the downhill row, do the same: hit every third ball until you take 18 shots.

Only balls that land and stop in a 6-foot wide target area, 5–15 feet from the hole, count as a success. Same target for both rows.

Count all balls that stop in the target area.

Add up your total successes and enter your score in the app, out of 36 attempts.

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.

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.
