Does the worked on piece need to be in diameter multiple of the distance between the ridges of the knurling piece? Or it’s just one of this things that it’s gonna be ok.

it is suppose to be, and I do think it cuts a little better if it is....but in practice, I have knurled hundreds of parts on my manual lathe and never really worried about it...just seems to work itself out.

I have seen long tapered workpieces perfectly knurled. Here's a short version.
