I read the tuning guide and it was pretty close to the way I set up my 14 at the Mega. I liked the method of measuring side shroud slop. I assume that you are using all standard issue shrouds and bridle. It is a very nice guide.
After sailing a 16 for so many years it was kind of strange to look leeward going upwind and see the shroud chainplate almost laying down due to slack.
