Length ratio is calculated by the amount of oil in the beginning to the pattern, divided by the amount
of oil at the end of the pattern. Also known as the Lengthwise Taper controls the variety of angles
different bowler types can use when competing. Refer to
Figure8-2.
a. Strong lengthwise ratio means there is more than 3 times the amount of oil in the beginning
of the oil pattern than at the end of the pattern. This creates more angles that players can use to
compete on a pattern.
b. Weak lengthwise tapers means that there is less than 3 times the amount of oil in the beginning
of the pattern than there is at the end of the pattern. This forces more bowler types to play the
same or similar part of the bowling lane. This is more common for recreational and competitive
patterns.
