The npoint() call in path will fill in individual lengths however with enough rounding error can lead to the final point at 1.0 not matching, but this also holds true for the second to the last point as well. And when that point fails there is no routine to correct for this oversight.
Error turns out to be that if a segment didn't actually affect any of the sectional points it failed truncated and didn't do the calculations but also failed to add that segment to the length.
