People are dunking on the fact that "mathematically optimal" is meaningless in this situation.

Even Lopez-Alt suggests, "It matters far more for winning internet debates and solving interesting math problems than it does for cooking."

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!
