I'm glad you figured that out! I don't know how many endless spirals I've knitted doing socks and sweaters and hats but I do know I still count stitches to make sure it's coming out right. It's easier with ribbing. If I'm up or down a stitch at the loop (yeah, what do we call it? The more or less half-way point?) it's obvious. If after a couple of rounds you're not doing it anymore you're a much better knitter than I am. You probably are anyhow.
