* help

I would like help with this pattern.
I start with 23 stitiches and do basic knitting and pearl for 2 rows.

Then the following K2, slip 1, K1, psso, K1, inc2, k1*, slip 1, k2tog, psso; repeat from * to last 4 stitches, end at **; slip 1, k1, psso, k2.

I begin the row and go to the first psso, go back to the first asterisk and continue to psso again, I end up with 21 stitches and when I get to the last 4 stitches I am not at **.
did I follow the pattern correctly.

I think you may be misreading it - st by st, here’s what you do -
k2, sl 1, k1, psso (k1, inc 2, k1, sl 1 k2tog, psso, k1, inc 2, sl 1, k1, k2tog, psso) Repeat the part in the parentheses, but on the last time through you only repeat the section k1, inc2, k1 part of it and end with sl 1, k1 psso, k2.
