Ah shucks ... on second thought don't think that chord formula will work by
dividing it because while we would be talking about chord lengths, don't
think they would divide correctly because the total chord length at it's
angle wouldn't be the same as the individual chords at their angles. Oh
forgot ... yes I need even and odd hole counts. What do you mean by linear
offset solution?
