Oil Predictability is a measurement of the durability of the conditioner and reflects how long it holds up in the oil pattern before it begins to deplete and change the performance characteristic of the lane. More durable conditioners will have higher ratings.
Back-end Predictability reflects the stability of the entry angle on the back-end as a result of carry-down beyond the end of the oil pattern. On conditioners with higher ratings, balls will respond less to carry down and have more consistent back-end reactions.
Speed Loss quantifies the resistance against the ball as it travels through the oil pattern. Conditioners with lower values match up better with more aggressive lane surfaces, while those with higher values can be a better match on lower friction surfaces.
