Sometimes pictures, or in this case a picture and a video, explains it best. The video below is the championship match of the Trio’s event at the recently concluded WTBA World Men’s Championship. The picture is the Kegel LaneMap™ of lanes 11-12 at Dream Bowl Palace.
The final match was played on the WTBA Mexico City oil pattern which is fairly flat and 45' in length. Our after bowling tapes showed the optimum breakpoint was around the 10-11-12 boards on that oil pattern at this championship.
The ball tracks of the left-handers and right-handers during the trios championship match are on top of the LaneMap™ Slope Graphs.
Sir Isaac Newton, the father of gravity, was not surprised with the ball motion of the players during this match - Newton has known for a long time that gravity has the same influence on the bowling ball as friction, or lack thereof.
The green areas on the LaneMap™ have very little gravitational influences on the bowling ball. The light blue and orange areas are significant gravitational influences on the bowling towards the direction of the arrows. The red and dark blue areas are severe gravitational influences on the bowling ball towards the direction of the arrows.
Now watch the video below and see if you can see and understand what Sir Isaac Newton already knew. He has been whispering in our ear for many years that it's not always oil or lack of oil (friction), as the reason the bowling ball reacts differently from one lane to the next, or even in certain areas of the same lane.
Pay attention to the right lane and how many light hits the right-handed players have. Then look at the above Slope Graphs in the break point area. Those blue areas signify a significant slope to the right - which is why the ball has a hard time moving to the left. Slopes to the right beyond the oil pattern (for a right-hander) acts like "carrydown". But it's not carrydown causing those light hits - it's gravity,
