I lofted the offsets for the Guillemot from "THE BOOK" and have run into a "snag". (Oh look, I'm using "paddling" terms already. :p )

Buttocks #8 on forms 9 & 10 put the 8in point at 5.22 and 4.46 respectively. When I include the additional-not-in-the-book points from the website "Book corrections" page these two buttocks points seem to be off from where the form outline should be drawn. For these 2 points to be on the form outlines they need to be around 5.70 and 4.80 respectively. Including them in the outline as-is makes a "dip" in the form outline at these points.

Unless the lofting points at buttocks 8 are where the form tops can be cut off for the cockpit decking? The offsets chart isn't really clear on this nor are the details in the text (or on the corrections page) very clear that these are the points that are intended to indicate that the forms can be cut off at that height. So, are they?

The lofting process was easy, this just seems to be either a printing mistake or I'm misunderstanding something.
