Obviously a nit-pick and I knew that when I posted it. Hence the LOL. But a shop might write 100 million SMF records a day. These instructions will get exercised for most (IEFU83) of them. Even one cycle per tends to add up. I have had to learn the new way of thinking: instructions don't count; storage references count. An unneeded reference to storage is potentially very wasteful of cycles.
