Or are they?
The major factors to consider when setting up, is the awkward distances as I call them, I am talking about the 11/13 yard and 42/43 yard targets loved by course setters, these seem to be the ones that can catch you out in range finding as they are usually where your trajectory is at its greatest rate of change through the scope line, plus your difficult range finding distances as TENCH mentioned, and added to that the factor of mini kills and your into a heading into a scramble of compromises.
