Have to put it down

I am about 4 inches in the the German Stocking pattern from CookieA and I didn't look at the errata. So, instead of doing the 1x1 ribbing at the cuff, I did 1x2 which was on the pattern. I felt like it was wrong. My gut kept telling me to look at the errata, but I didn't I just kept on knitting. So here's the dilemma, do I keep on going and add elastic to the cuff to tighten it up or do I frog back? I am putting it down for the night and will think about this over night. I'll let you know what I decide.
