Berkley love underrating the strength of their braids - I can only imagine they continue to do it, as it maintains a rep as a super tough line. (and coz they've always done it to varying degrees on their range)

Their 4lb Berkley Crystal used to break at around 12lb aswell.

I believe the original reason was when braid was introduced to the market, they used to compare the diameters between braid and mono. So it was easy to just state their braid was as thick as 4lb mono - so they called it 4lb.

Maybe European and Asian markets have asked for actual breaking strains, like so many other braids already do.

The red numbers are Breaking strain stated on the packet - and the blue number, 3 columns over, are what independent tests show
