> I trust my code to be optimal, or I know where it isn't and leave it at that

That's a pretty remarkable claim, unless you religiously profile all of your code.

Well, it's optimal, not optimized. So let me re-phrase that in a way that's more realistic - I trust my algorithm choice to be optimal, and my code expresses those algorithms in a simple way, which get a good speed to cleanness ratio. :)

I still say that's a remarkable claim. Modern computers are complicated (not to mention language runtimes and frameworks), and few applications admit straightforward algorithmic analysis.
