Hi,

I have a PolylineCurve, which one point was moved by the gumbal, and thus the curve was shortened form 6 meters to 2.249 meters. When I try to find discontinuity G1 locus continuous, the final parameter is given on a distance of 6.00012 (original length) while the new length of the curve was not given correctly. Eventually I end up with final knot in different place than total length of the curve. Can you advise if I’m doing something wrong here?

Rhinoceros 6 beta

```
var discontinuities = new List<double>();
var t0 = curve.Domain.T0;
var t1 = curve.Domain.T1;
discontinuities.Add(0);
while (curve.GetNextDiscontinuity(Continuity.G1_locus_continuous, t0, t1, out t0))
{
discontinuities.Add(t0);
}
```

Another issue that I have is, that knot value is often slightly greater than curve length. I am also not sure if this is a bug or expected behaviour.
