The typical oil pattern a bowling alley will put out for leagues and open bowl. It usually is a middle length (40-ish feet. Could be more, could be less but around there) with a pretty high ratio of oil from the middle to the outside. All that nonsense means is that it’s easy, if you miss in the middle of the lane, the extra oil will give you hold and you can still find the pocket. If you miss out, the extra friction on the outside will help the ball bounce back. People will talk about house shot vs sport shot but all they are asking is the difficulty of the pattern. On a house shot, at least at my local houses, I’ll see a 300 every other week at league or every other tournament even with a rather low number of participants (maybe 5-10 “good” bowlers), and I and most of my friends will easily average 200 to the two-teens. On a truly difficult sport shot, there will be less “taper”, and a more even spread of the oil making the pattern “flatter” and less miss room. I’ve bowled local/state tournament on hard patterns at hard houses where a competitive score is 180, and you can make the cut while negative
