ARROWS /
ARROWS BOARD
SPECTO TERMS
Board at which the ball is located at the arrows (15 feet).
BREAKPOINT BOARD
Board at which the ball was at its outermost position.
BOARDS CROSSED
Total number of boards the ball crosses on the way to the pins.
AVERAGE SPEED
The speed calculated using the time it takes from Launch to Entry, divided by distance traveled.
BREAKPOINT ANGLE
Total angle between launch and impact.
BREAKPOINT DISTANCE
Distance at which the ball was at its outermost position.
CUSTOM POSITION
Ball position at the custom board marker which is the second arrow from the left underneath the lane graphic.
BREAKPOINT LENGTH
Distance the ball traveled on the breakpoint board. Shorter length means faster ball reaction, longer length means slower ball reaction.
CUSTOM SPEED
The speed calculated based on the custom position marker located below the lane image.
ENTRY ANGLE
The angle of the ball between 51 and 55 feet.
ENTRY BOARD
Ball position at 59.5 feet.
ENTRY SPEED
The average speed of the ball between 57 and 59.5 feet.
FOUL LINE
Calculated board position of the ball at the foul line based on the launch angle.
FULL RACK
Shows you if it is the First or Second shot.
HOOK
The length at which the ball is changing its direction.
HOOK BOARD
Board position of the ball where it started to change direction.
HOOK BOARDS
a.k.a HOOK POWER
Number of boards the ball hooked based on the True Breakpoint.
HOOK SHAPE
Percentage of total hook. Higher numbers indicate more angular motion, lower numbers indicate more arcing ball motion.
IMPACT ANGLE
The angle of the ball between 57 and 59.5 feet.
LAUNCH ANGLE
The angle the ball traveled the first 10 feet
LAUNCH AXIS
A beta item that should indicate the axis that is calculated when putting a piece of reflective tape on your Negative Axis Point. Righties should be on left of sensor, lefties on right
LAUNCH SPEED
The average speed of the ball in the first 3 feet of readings.
LOFT
Point when the sensor reads over 60% of the ball surface for the first time. This number can change significantly based on the amount of the ball that is seen so can be inaccurate.
MAX ANGLE
The largest angle of travel of the ball on the lane.
MAX ANGLE DISTANCE
Distance where the ball hit its maximum angle.
MAX HOOK ANGLE
The amount of hook in degrees at the point the ball made its largest change of direction.
MAX HOOK DISTANCE
Distance at which the ball changed its direction the most (Max Hook Angle).
Indicated by a yellow hash mark in the coaches app.
MAX SPEED LOSS
The distance at which the ball lost the most speed.
PATTERN EXIT
Board at which the ball is located at the pattern exit point, based on the pattern length set above the lane image.
PIN DECK DEFLECTION
The number of boards the ball deflected in the pin deck.
PIN DECK EXIT
Ball position at the end of the pin deck.
LAYDOWN POINT
Calculated board position of the ball at the foul line based on the launch angle.
PIN DECK SPEED
The average speed of the ball in the pin deck.
PINFALL
Total number of pins that fell. Only available in centers enabled with LaneTalk
REVS / RPM
Calculated revolutions of the ball.
READ
The distance on the lane at which the ball first slows down.
ROLL
The length at which the ball stops the Hook phase, which is where the ball stops changing direction significantly.
ROLL BOARD
Board position of the ball when it completed its change of direction.
RPM TO SPEED RATIO
A number that tells if the bowler is speed dominant, rev dominant or
if the speed matches their revolutions
RPS - ROTATIONS PER SHOT
A beta item that should indicate the number of rotations the ball
makes going down the lane. Assumes the ball reached the Roll stage, otherwise can give inaccurate readings.
SHOT
Total amount of time in seconds the shot took.
SHOT TIME
Indicates what shot number you are on.
SKID
The length at which the ball does not change path significantly.
SPEED LOSS
The difference between the Launch Speed and the Entry Speed.
SPEED LOSS BACK
The speed loss from 40’ to 60’.
SPEED LOSS HEADS
The speed loss in the first 20’ of the lane.
SPEED LOSS MIDS
The speed loss from 20’ to 40’.
SPEED LOSS PIN DECK
The speed loss through the pin deck.
TOTAL HOOK
Total number of boards the ball hooked compared to a completely straight
shot.
TRUE BREAKPOINT
Distance at which the ball was farthest away from the direct path to
the pins. When drawing a straight line to the pins this would be the distance of the
largest shape.
Indicated by a red X in the coaches app.
