Question-Button band on cardigan

Hi Everyone,
this is my first question on this forum. I introduced myself earlier today where I mentioned that my first major project is a cardigan. Here is a link to the pattern:

I'm almost finished. I started the button band last night but I don't think I did it right. The instructions say to pick up stiches along the neck and front edge (4 stiches for every 5 rows) and to place a marker at the point of the V-neck. Then to knit in 2 x 2 rib pattern and increase one stitch at the marker and then continue in the 2 x 2 pattern for 4 more rows and bind off.

Am I supposed to increase one stich for every row? I didn't do that and I had a big bulge in the body of the sweater at the point of the v-neck, i think because the button band didn't have enought of a 'curve.' If i add a stich for every row, that will throw off the 2 x 2 pattern, unless I just increase the number of purl stitches at that point in every row and maintain the ribbing pattern. That would mean a larger band of purl stiches at that point (it happens to fall where the ribbing pattern is at a purl stitch)

Anyway, I ripped it out because I didn't like the way it looked. Would blocking take care of that?

Does that make sense? Any suggestions?

Thanks!
