Ok, so how could I make it one line ?
Are you sure it's 3 lines? In this case I should have 6 points instead of 4 I think.

Nope, 3 lines can share points and so still have just 4 points.

In your case, the simplest way to build a single curve from the segments is with either a join or polypath sop.

Edit:
The join sop does not remove redundant vertices.

Try lowering the curve density, reducing the mass, and increasing the number of constraint iterations.

Generally, the number of required iterations increases with the square of the number of points per curve. The apparent mass of the curve also increases with the square of the number of points. Reducing mass increases the apparent stiffness of the curve.

Mantra doesn't use absolute units for light intensity, all units are relative to the final pixel intensity. Physical effects such as sensor sensitivity (ISO), exposure duration, and aperture have been factored out. So asking to quantify light using an absolute metric would first require quantifying the other physical factors. It can be done, but to me sounds like needless complexity. I can see why you might want it if you must match certain real world measurements though.
