I'm not disputing your observations, but from a materials/manufacturing standpoint it just doesn't seem practical (possible yes - but not cost effective).Fact is I noticed it on both plain and wound strings, or I would have written it off as difference in core thickness under the windings.
Not much difference, but I estimated up to 5 cents longer throw needed on the plain LSS compared to the same-gauge plain Jagwires. Not bad compared to other brands I have tried, and I'm still talking about plain strings.
That would mean they are drawing their own wire, a hugely expensive undertaking (I have close family in the wire business and we've discussed these things).
Only a few of the largest string makers draw their own wire, as machines to draw thin wire to the kind of standards necessary for guitar string manufacturing run close to a hundred thousand bucks - and up. And several are required to cover various alloys and gages.
For a small manufacturer to draw their own wire is simply unheard of - the string cost would be astronomical. This is why nearly every small string label is just that - a label, with the strings manufactured by larger outfits with custom ball "ties", thread colors, wire colors etc.
Some small makers "wind" their own, but buy out 100% of the wire they use from wire manufacturers.
For a small brand to consistently supply plain strings that are 5% different in tension would require equipment...and selling prices...that would make no sense.
