Interweave's Mommy Snug Question?

I’ve finished the front and back of the sweater and am working the sleeves at the same time. I’ve changed them to not include buttons and button plackets, but I just finished the part where you end the button plackets and start to increase.
I am at “Shape sleeve” and have a question. It says “Working incs as directed in Stitch Guide, work inc row every 4th row 4 (13, 0, 8, 10) times, then every 6th row 8 (3, 12, 8, 8 ) times.” In the Stitch Guide, it has instructions for 2st increases for 4 rows. I assume that I do the first row increase once, then 3 straight rows, then the second row increase, then 3 straight rows, then the third row increase, then 3 straight rows, then the 4th row increase, then 3 straight rows, then repeat that process again once for my size [in bold].
