Find A Specific Distance Between Among Multiple Intersections

Hi, I am hoping there is an easy solution for this.

I have created a tool that gives me the intersection points among a number of lines that I want, but now I want to only find specific distances among those intersections.

Attached is a picture of the output in Rhino, with my notes overlayed as to the distances I am trying to extract in green brackets

In the attached picture, each of the arrayed horizontal lines have multiple intersections along them, but what I would like to extract is the distance between each intersection on the right, with the FIRST intersection to the left (measuring right to left).

I also attached my GH file.

Any help would be greatly appreciated.
