In spare set #472 the ten leaves come in this order: 1-2-4, 1-3-6-10, 1-3-6, 4-7-8, 6-10, 5-9, 3-5-6, 10, 3-6 and 4. One ball for each, and every clear counts.
We rolled each of these leaves 48 times with the Hard computer's aim and errors. On this set it cleared 23.6 out of 48 on average. The kindest leave here is the 3-6 leave, cleared 31 times out of 48; the toughest is the 1-2-4 leave, with only 17.
The set includes a corner pin (1-3-6-10 leave, 4-7-8 leave, 6-10 leave and 10 pin). Shoot it from the other side of the lane so the ball crosses towards it at an angle. The widest leave, the 1-3-6-10 leave, has pins far apart across the lane; it needs a pin to slide across and take the other. Clusters of three or four pins (1-2-4 leave, 1-3-6-10 leave, 1-3-6 leave, 4-7-8 leave and 3-5-6 leave) fall to a ball aimed at the pin closest to you.
A friendly set: straight balls from the opposite side will clear most of it.
