Row 4 should decrease it - k 3 sts, then pass st 3 (counting from the tip) over the other 2 just like when you BO. Round 1 increases sts btw, unless there's a k2tog somewhere, so that may be why you feel like you're not losing stitches. If you can post a link to the pattern we can have a look to see if you're interpreting it correctly. The top decs don't start until it's about 7" from the beginning - is that where you're at?
