That's far from clear: you're ignoring the possibility that memory access logic is better optimized for forward scanning than reverse scanning. I'd stick with the forward scan without some extremely detailed testing.
I don't disagree.
After posting, I was wondering if the first possible is not zero, it should probably be at the beginning and not at the end.
