Yep;its why I started with the calculations.
I have 2 "5 metre" sails.
A Gun MC wave and a NP Combat. The Combat is lots better in strong winds; the Gun loads more bottom end.In theorey both 5 metres but on my scale the MC comes out around 75; the Comat around 70.(Similar aspect ratios too !!!) So obviuosly the Combat is better in strong winds ; its smaller !!! (Both 5 metre sails can go in same quiver !!!)
My biggest sail is 7.5 metre (107) but compares favourably with most 8 metre sails on my scale. My 7 (in theory only half a metre smaller) scores only 97; so it fits in my quiver.
