At the very bottom of the Professional Bowlers Association points list is a player who has never won a title. Put him on the lanes you bowl on, and he would average around two hundred fifty.
The gap between a good league bowler and the worst professional is not close. It is not in the same universe. And the number you are proud of is the reason you cannot see it. A typical house shot loads the middle of the lane with oil and leaves the outside dry, a ratio that runs anywhere from seven to one up to ten to one. That ratio funnels the ball to the pocket and quietly corrects your mistakes. The patterns the PBA bowls on run closer to two to one. No funnel. Every mistake stays a mistake.
Strip the oil and the scores fall apart. The United States Bowling Congress publishes a Sport average conversion chart because a house average and a sport average are not the same currency. The best pros on the PBA tour hold around two hundred twenty-four on that tight oil. Run the math backward onto a house shot and the worst full-time professional in the field is a two hundred forty to two hundred fifty bowler on the lane you call hard. A professional holds his average on any pattern, in any building, on any night. A league bowler holds it on one specific pattern, painted one specific way. Those are two different sentences that happen to share a number.
