Agree with what you are saying Nako but even taking (slightly) different plan shape of sails into account there is still no way the two sails mentioned are only 0.2 m different in size !!!
IMO manufacturers build different styles of sails and then "manage" the sizes to accomodate the desired outcome. (Eg Power wave sails are always bigger than normal wave sails) Ezzy are designed to be good in strong winds so they build them small !!!
Sails are not flat but all sails require a certain amount of material to build them; I`ll guarantee manufacturers know exactly to (high degree of accuracy) how much material goes into the sails ! ie when they pay for materials) Anyhow its still not an argument for not measuring sail area correctly;its not difficult !!
