A big miss really depends on the bowlers accuracy. Some bowlers are aggravated if they miss by 1-1/2 to 2 boards either way. While other bowlers play a general area (ive known bowlers who's goal based on where they are standing is just to get it between two arrows, and a miss for them is outside of that area).
So it's variable based on each person. I myself like to keep it within 2 boards of my target area. I also have a tendancy to miss left as opposed to dumping it right (timing issue with fast feet).
With the way I line myself up on sport conditions I am usually up the back of the ball more (it gives an earlier but less aggressive back end reaction that way), and I usually play as tight and straight as possible, at least to start.
If I tug it left 1-2 boards I am usually ok though I know it will check up early, but if I tug it more than that the results are usually bad
