You’re welcome.
Please know that my goal here is not to do any hand-holding, but only to point you in the right direction. (But I’ll admit the ‘Rinterp to’ rabbit hole was a dead-end direction)
Fifty replies back and forth - UNPRECEDENTED.
I’ve been in casinos and on cruise ships, watching old-timers play the slots. These machines fill me with a sense of sadness. What’s the point? Where’s the strategy? What gods are we serving by re-creating a random number machine?

I think I get what you’re saying about the positioning. The ‘Map Ranged Clamped’ is probably non-essential. Working with 0-360 values seems like a good path as well.
If you share the textured 30-sided wheel I’ll plug it into my test project and see what I see. (But only in a ‘I’m curious to poke at this’ way and not in a hand-holding way!)
