What is a good system for aiming fast-speed bank shots?

The twice-plus-tenths bank shot aiming system illustrated and demonstrated below works well for sliding banks resulting from fast speed or the OB being close to the rail. It works well for banks of any speed if the OB is close to the banking cushion (where it doesn’t have time or distance to develop forward roll). Alternative names for the system include “2.2x” or “twice plus 20%” or “twice plus 10% of twice.”

Twice-Plus-Tenths Sliding-Ball Bank Shot Aiming System

For more information, see “Twice Plus Tenths” (BD, November, 2023).

An alternative to the twice-plus-tenths system, which measures everything relative to the rail grooves across from the diamonds, is the 1-more-than-twice system, which instead measures everything through the diamonds. This system requires adjustments, but it might be preferred by some people.

In addition to being able to use the aiming systems above, there are advantages to using fast speed with bank shots. For more info, see: advantages of fast speed.
