Now I'm itching to try this. I'm wondering if on the half herringbone the WS would be *Sl1, yo, k2 tog*. I think there are slipped stitches. Maybe. LOL
ETA: This comes close
multiple of 3 + 2
I CO 14 sts
Row 1: K1 *K1, yo, k2 tog* k1
Row 2: K1 * Sl1, yo, k2 tog* k1
The k1 at each end was for an edge stitch and not part of the pattern.
