The mathematical verification doesn't matter, but:

* Radial is more convenient than the classic horizontal cut.

* Radial with an origin below the cutting board is a better outcome than naive radial with almost zero extra effort.

All this to say: it was worth figuring that out!

Except:

* The spacing and angle of your cuts is going to vary much more if you are doing something more complex than top down cuts negating any gain in consistency.

* The outcome of the final dish isn't really any better so it doesn't matter at all.
