Thank you. To be honest I just blundered my way through. I used this link http://www.getknitting.com/ak_0601magicformula.aspx to work out my decreases, my first sleeve wasn't quite right so I just adjusted it slightly for the second one and it turned out. I finished with 2 knit 2 pearl ribbing for the cuff. Hope that helps.
