Recently, Coord.distance() was replaced with a much speedier implementation because a lot of cpu cycles were being wasted there. The newer function appears to be accurate enough for our purposes.
The DP code contains another distance calculation. What you must calculate there is the distance of one point to a line. The Coord.distance() is used in that formula, but I do not understand the formula itself. Maybe it's some genius trick to simplify the calculation, but I do not get it. The only thing I see is that when I reduce the error distance the simplified ways look "nicer". But the preset error distance of one half of the resolution should be small enough already. So my assumption is that the actual error distance is much larger than expected, which may be due to a bug in the code.
