Thanks, Jospeh and Kim!
I wish I could say this was the right solution but I think I did get started on the wrong path and your expert advice lead me more expertly astray.
I think maybe Orient Direction is a better tool. This is a garbage example, just using internalized points and not actually referencing the curve but I like how changing the vector length changes the scale proportionally. What I’m primarily after is the proportional scaling (I didn’t make that clear) equal spacing and propper orientation along the curve.

In a straight line example, I think this applied to the helix with some level of variation over the percentage of scale increase, and spacing, would be rad.
I’m not sure how to get there with the limited functionallity of Point On Curve. I’ve always wondered how to get move a point along a wavy curve at specific lengths.
