How long is each yo section supposed to be? Do you have a pic of the pattern to see how long that “leg” is supposed to be? And are you supposed to end up with four more stitches or 12 in the next row?
What Sue said, or, from some of the other lace patterns I’ve been swatching recently, it could be:
(k1, p1, k1, p1, k1) WITHOUT slipping the first yo loop from the left needle to the right, until all five stitches are done on the loop – when you’ve made all five stitches into the first yo, slip the yo off the left needle to the right needle, then repeat in the next yo until you’ve done all three yo loops. (You’re basically knotting the active thread around the base thread.)
Sorry if this isn’t very coherent, I’m in bed sick today…
