I'm glad I wasn't the only one who spotted that.

There's something very curious about somebody worried about efficiency 
choosing a *less* efficient solution than what they started with. To 
quote W.A. Wulf:

"More computing sins are committed in the name of efficiency (without 
necessarily achieving it) than for any other single reason — including 
blind stupidity."

As Donald Knuth observed:

"We should forget about small efficiencies, say about 97% of the time: 
premature optimization is the root of all evil."

The Original Poster (OP) is concerned about saving, what, a tenth of a 
microsecond in total? Hardly seems worth the effort, especially if you're 
going to end up with something even slower.
