Oh spirals are not easy

Imagine I’v made spiral curve. I then split it at specific level (it should be adjustable) it gives me a point.

I now building a second spiral curve which should finish at the point I got from splitting first spiral.

So what I did, I subdivided lower portion of the first curve and found and angle between first two points it gave me a total angle which I used to create second spiral.

The problem is I don’t have control over how many revolutions I have (in second spiral) and if I change the height of spitting it all goes to nothing…
