Help with pattern

Hi everyone. So I’m knitting a cardigan and have come to the sleeves. I’m stuck on the part I’ve circled. It says to increase on every 10th row but there are 11 rows and the increase is made on the 11th row. So I guess what I’m asking is do I increase on the 10th or 11th row? I have attached screenshot and hope I’ve explained it simply lol
Thanks for any help

You explain it very well. The patterns Row 11 given you the stitch placement of the increases at the beginning and one stitch from the end of the row. But from now on you’ll be increasing at each edge on every 10th row (rows 21 and 31) rather than every 11th.

Thankyou :blush:
