Prior to applying the lane conditioner (oil) the machine will typically clean or strip the old oil off the lane. So, there's oil where it "should be" as well as dry or "friction" where it should be, too.
With today's equipment this is optimal because the oil allows for "skid" and the dry allows the ball to "grab" and to travel in the direction of it's rotation.
The main thing the bowler has to determine is how soon he needs to encounter friction for optimal carry; too soon and sometimes the ball loses energy and rolls out; too late and the ball may not make it to the pocket.
By adjusting the cover to around 2000 abralon it should start reading the friction area earlier than a polished ball, yet still retain enough energy to hit and carry. Every bowler has different ball speed and rev rate that contribute greatly to how the ball "reads" the friction or dry area.
The surface of the ball is important because, simply put, that's what is in contact with the lane surface. Have your pro shop watch your ball on the lane to make certain that you're taking advantage of the friction properly. They may also be able to help you if the physical aspect of your game needs fine tuning. Good luck.
