The ABS and Distance.15 is some "trickery" to make it work with PBP but the "clean" formulas shuld work fine with pen and paper. Try it out, make it work with the 12 hour clock example you actually asked for first. Then try wth the larger numbers, I'm sure you'll be able to figure out what needs tweaking for any number of ticks around the circle.
You were interested in the logic. This, I think, is one way of doing it but I'm sure there are others. As for how to actually implement it on Oshonshoft you're on your own or at least in the hands of someone else.
