This question is for individuals that regularly put out the shot in their house.
I bowl in a 5 Man men’s league, part of our league follows a 3 person mixed league while the rest of the league bowls on a fresh shot that is applied 2 to 3 hours before we start. The 6 lanes that are used by the early league are stripped and oiled right before we start. There is a noticeable difference in the way the pattern plays from the lanes that are used in the early league and those that were not. The lanes used by the early league play much tighter than the others. The house claims that they use the same shot for all the lanes, but the play is greatly different.
What causes this difference?
