Indeed, not to mention C vs. ASM.

I would like to know how much slower the portable solution you proposed is as
compared with the ASM code.

Sorry that I couldn't resist joking, but just try to read the code aloud.  When
I used ASM, mnemonics were made of only 4 or 5 letters.

With so many rounds Fruit is bound to play Jonny at some point despite the
latter's bad overall score, so anything can still happen.  One could say that
thanks to this, Jonny still has a (good) chance to qualify, as it deserves.
