notclay is correct. I can program the machine to run a 5 foot pattern or a 55 foot pattern. I can program it to put no oil outside 10 on both sides, 1 side, or flat from gutter to gutter. There is no one singular pattern that the machine will lay out and if there is, there will be differences between the environment the bowling alley is in, lane topography, and of course, the type of oil used. Thus, someone could take a singular machine, put down a pattern in one house, take that machine to a different house, use the same pattern, same oil, and the results could be drastically different.
