I think line companies already do that. I've read a lot of comments over the years saying such-and-such line is "the strongest 8# line you can buy". Well, it's probably not 8# line. It's probably 10-12# line with an 8# label.

FWIW, I pay more attention to the diameter than the pound test. The stated diameter could be off too, but something measured in thousandths of an inch will be more accurate than 4# or 6# or 8#.
