Length along Path seems not valid

[David Arnold]

Using the Length along SplinePath Tool:

The first image shows the bigger picture, the blue dotted line on the bottom are the reference lines, used for measurement. The second enlarged image shows the transition of the points from the blue reference line onto the Spline Path. As it can be clearly seen the path-bound distance between those two points on the Spline Path do not match de reference distance.

Addendum, trying to increment the segment distance of the second point (the one on the right) by manual increments in the cm range does not move the point. It seems a possibility that this point might be calculated correctly, but for some reason can not be moved beyond the depicted extreme on the right.

Cutting produces always two sub-paths.

if (length < GetLength()*0.02)
{
    length = GetLength()*0.02;
}
else if ( length > GetLength()*0.98)
{
    length = GetLength()*0.98;
}

Do I read this right, that cutting is limited between the section 2% to 98% of the cuttED path's length?

I assume this is a technically necessary operation. Would it be very costly to lift that to 0,001 % and 99.999% ?

Yes, i think this possible. But better create unit tests and check if all is ok.
