When a bowling ball is traveling down the lane, it has to do one thing for it to react properly...It has to slow down. If a bowling ball does not or is allowed to slow down, it will not be able to change direction. It can't. It will either continue to slide or skid out, giving the look that it is straightening out or even fading away from the lateral direction it was traveling.
When most bowler's see what they perceive as carrydown, most of the time the bowler does not have the correct bowling ball in their hands. It takes very little oil in the rreaction area of the lane to cause the reaction to be altered.
If the ball decelerates in the front part of the lane, by the time it sees friction, any amount of conditioner will effect the motion or 'push' it off line.
The amount of conditioner that travels down the lane is minimal. But when a ball is traveling on fresh surface, this amount of conditioner will or can effect it.
Different synthetic surfaces have different friction levels. AMF is generally the highest potential and Pro Anvil lane is the lowest. If oil dissipates on a high friction surface, generally it makes the lane appear as overreacting. On a lower friction surface, it gives the perception of overskidding. As well as, oils travels on the lane surface differently, some dissipating entirely or staying on the bowling ball surface. Many have different additives which effect how much the ball stays on top on the oil or cuts through it.
Generally the bowler uses too much surface on most conditions.
