Help spacing picket on a fence

[rickgplus]

yes i've tried a few values, but never quite got it right. I'm assuming the 'bounds' offset throws the spacing just enough to make it inconsistent. Is there a way to ignore the bounds of an input mesh, and space each point at absolute distances? Or maybe I can use an empty input into bounds or a dummy object?

Fairly new to curvy so I'm assuming I'm missing something obvious.

Alternatively, if its possible to add some kind of script that will lengthen every n number of pickets that would be doable as well.

I am only using one custom object at the moment. Attached in .zip
