I agree that looping would burn some time, which is why I would use delay() for most, but not all, of the delay. I assumed a more general case, where processing time for each iteration could not be precisely specified. The CPU load might be higher or lower, causing processing (not delay()) to take more time, and throw off the timing. This is why, every time the loop iterates, I start with a gross delay(), followed by fine-tuning in the form of a "wait until _exactly_ one second since last loop". Blaq!
