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

Make 10 piles of 4 balls (40 balls) in two lines, crossing each other near the green, 1 to 10 yards from the green and 5 to 30 yards from the hole. Keep piles 2 yards apart, lines 5 to 10 yards apart.

On the green, use string or tees to mark two circles around the hole: one with a 6-foot radius (inner), the other with a 15-foot radius (outer).

Use only 36 balls (9 piles of 4) for this test.

Split the 36 shots into two groups of

For the first 18 shots, try to land the ball inside the small circle.

For the next 18 shots, try to land the ball inside the big circle but outside the small circle.

Play bump-and-run shots by hitting from different piles, one after the other, keeping the same setup and order.

Count as a success if the ball stops in the correct circle. If not, it is a miss.

Count how many balls finished where they should in both circles. Enter your score in the app, out of 36 attempts.

Place two straight lines of 18 golf balls each on flat ground near the green.

Space the lines 5 yards apart and put them 5 to 30 yards from the hole.

Hit 36 bump-and-run shots.

In the first line, hit every third ball, skipping the two in between.

At the end of the first line, switch to the second line and do the same. Alternate lines until all 36 shots are hit.

Place three target zones on the green in a line.

For the first 12 shots, aim for the closest target zone.

For the next 12 shots, aim for the middle zone.

For the last 12 shots, aim for the farthest zone.

Count each shot that lands and stops in the correct zone as a success.

After 36 shots, total your number of successful shots out of 36 and enter your score in the app.

Place 18 balls in a row on the fairway. Place another 18 balls in a row 5 yards away from the first row.

Label one row “Above Feet” and the other row “Below Feet” according to the slope.

Divide each row into 3 zones by distance: Zone 1 (5–13 yards), Zone 2 (14–21 yards), Zone 3 (22–30 yards), with 6 balls in each zone.

Hit all 36 balls: start with all balls in Zone 1, then all balls in Zone 2, then all balls in Zone

Take turns hitting every third ball from one row, then switch to the other row and do the same.

Try to stop each ball as close as possible to the hole.

Count each ball that stops within 3 feet of the hole as a success.

When finished with all 36 shots, record the number of successful shots out of 36 in the app.
