Usually depends on where most of the open play is put, how new or old the lane surface is, if they were all installed at the same time by the same crew, if the pin decks are all the same, location of air/heat units, outside doors and windows, proximity to outside walls.
Our low end, 1-6 are the highest scoring, 7-14 probably lowest scoring, and I prefer 15-16 over the middle of the house where a lot of our bowlers don't care for that end pair.
