Don Casey recommend the opposite approach in his book which actually sounds reasonable.
Since you are working from the outside and have a one inch hole on the inside flaring out to a 5" scoop it makes sense to start with a patch slightly larger than 1" and use slightly larger patches until you build out to the last patch being 5". The West video shows the opposite. Starting with a 5" patch that sort of bags in and each patch being smaller then ending up with the smallest on top. It looks back wards but the advantage is that more fiber is in contact with the patch.
I contacted Don about this and he said he ran tests and the West way (Scotty's way too) is stronger so he is changing his book.
So scotty is right even on this detail.
