Mast stiffness

Has anyone ever come up with a standard for measuring IOM mast stiffness? Something like cantilevering it off a workbench and hanging a can of tomato soup off the end and measuring the deflection. Something that anyone can do. It would be interesting to compare all the different masts in terms that everyone "can" relate to. I guess that internationally a can of soup wouldn't work but you get my drift.
Thanks
Don

Great info on the Sails Etc masts, has anyone tried the experiment on the Easton 7075 T-9 tubes?
