Super confused!

Wondering if I’m doing these instructions correctly.

Pattern says:

dec 1 every 3rd and following 8th row.

I’m doing sets of eight, decreasing at the beginning of the third row and then I continue to count to eight where I decrease again. Then I start counting to 8 again.

I am doing a front panel of a sweater and it’s decreasing at the front edge AND the edge where I will seam it to the back which doesn’t look right to me… Help!

You don’t dec every 8th stitch, but every 8th [I]row.[/I]

Dec on the 3rd row, then row 11, 19, 27, etc…
