Nope, b/c racing sails hold their design shape better for the first 5 years, then grenade in spectacular fashion, and you throw them away.
Cruising sails slowly lose their shape as soon as you use them, but they don't grenade or fall apart until 15+ years later. This is long after they've lost their 'foil' shape.
IMHO, dacron sails should be replaced anywhere in the 5-10 year range. 10 is the extreme, but people don't b/c they're expensive and not worried about pointing 5* higher and going .3 knots faster in every direction. In racing, that's huge, and people are willing to pay more for better performance.
Dacron stretches, quite a lot actually, and that's not good on a racing boat.
