I mean maybe but if you told me you could take my code that runs in less than a second and make it more readable but it would take 30 minutes to run instead . . . hell no I'm not taking you up on your offer. I'll just comment and document the existing solution better and call it a day.

You're missing the point.

The solution here is faster than the absolute naive solution of finding all distances, but it is both slower and less readable than integer math grid conversion..

I could see why you would make the choice of the naive, slow solution. I could see why you would choose the fast, integer math grid conversion one. But I don't see why you would choose something slower than the optimum solution that is also much, much less readable.

That is, the naive solution and the integer math solution are Pareto-optimal choices... and this abomination ain't.
