Yeah, I'm gonna rip it out and try it again. Wish I'd seen the errata sooner. I know better too :S
ETA I wrote that one down, it's not quite the same. I can't even find Barbara Walker's version charted. This one goes
K2, yo, ssk, yo, k3 sl1 k2tog psso, yo, k1, yo, sl1 k2tog psso, k3, yo, k1, yo, sl1 k2tog psso, yo, k2tog, yo, k1, yo, k3 and then the end 13 sts. Has 8 beg sts, 20 pattern repeat, 13 end sts.
goes back to ripping out and trying it again
