Grid based on two curves

Grasshopper

Hello, I’m a GH beginner trying to figure out a way to trace a grid based on two input curves following these few simple principles:

The idea is to have two different grids, both aligned to the initial curves. Elements on Grid A are supposed to be 12 to 20 ft apart, while the distance gets from 6 to 10 for Grid B.
I had been trying to do it manually on rhino, though I switched to grasshopper as soon as I figured how tricky that could get with narrow curves

The example on top is done on rhino, while at the bottom you can see the best I could could do with grasshopper for the same curves.
Here’s also a screenshot of the definition I’m attaching

Could anyone please give some tips on how to proceed? My experience with grasshopper is really basic and I’m stuck at this point.

There is no way in hell doing this with a perpendicular array

I know, that’s actually part of the issue. And that’s why I had tried using arcs instead, though it didn’t help much…

Thank you, that’s a pretty good one, except I cannot really get it to work with more complex geometries such as mine.
