A shot laid down in Chicago, will be different than the "same" shot laid down in Reno. there is more to a shot than the oil pattern. Lane Surface, outside temperature, inside temp, humidity, etc. If you know what you're doing, you can take a tough shot, like the one the ABC puts down for the tournament, and turn it into a nice little wall in a short period of time. If you're upset with the shot your home center puts down, complain to the manager, get your fellow bowlers to complain. If the USBC mandates a universal condition, proprietors simply won't sanction. If I spent $100K on a lane machine, I'm not gonna let some outsider (I don't care who they work for) come in and monkey with it.
