Note 1: The size of an index ball varies from a big one to a small one. In addition,
the center of the index ball is not always aligned with the center of a ball.
Then, to distinguish index marks one to four corner clearly, the index ball
position is set as follows:
When an index ball is on the ball cross pattern, it is handled as the
“Standard” type.
When an index ball is outside the ball cross pattern, it is handled as the
“Index mark one to four corner”.
Standard Index mark 4 corner Index mark 3 corner
Index mark 2 corner Index mark 1 corner Outer belt type mark Mark overspill

If you want to use a user pattern when you select the staggered pattern, regard
the staggered pattern as the standard pattern, and suppose that a ball is located
at an area on which no ball is located. The ball pitch becomes half of the actual
one. Enter this ball pitch, which is reduced to the half, and select a user pattern.
