I was talking about the cast on stitches. The increases along the raglan will be the same. But you start out with more stitches at the cast on row on the sleeve sections than you should.
Say for instance the CO is 90 sts for size small and you would divide them 30 for the back, 30 for the front and 15 each for the sleeves. But you need more stitches for the sleeves so you might CO 96 sts and divide them 30 for the front, 30 for the back, but 18 each for the sleeves. Then do the increases at the markets exactly the same.
