Alan - I completely 'misjudged ' you. Spent a needless 10 minutes reinforcing my case! I like these open forum discussions though -if they expose weaknesses in the rules.
As you know, in the SC it does state that the entry & exit before & after are indeed judged as part of a manoeuvre - but only if some elements of the manoeuvre are in the box. (my interpretation)
Where all the manoeuvre elements are outside the box - there is nothing to mark -so any entry & exits although they maybe inside the box, count for nothing.
A similar analogy might be, say, on a centre manoeuvre -say a full snap. The pilot does an excellent entry, excellent exit - but forgets the snap. Again the entry & exit count for nothing, because there's nothing to mark.
