Look at it from bar designer point of view
He anticipates that all the lines will become even when the kite is flying and that's what you want
This is an interesting theory.
Stretching / shrinking may take time.
If I understand the process, dirt, sand and salt crystals get in between fibers making them thicker and shorter.
So are you saying that designer wants you to fly an untuned kite meanwhile?
Stretching/Shrinkage is often a result of temperature changes. All things expand and contract with heating and cooling, kitelines are no different, what is an issue is differential shrinkage, one more than the other. Here in the temperate UK, we don't get a lot of massive temperature changes, but kiters travel and return and any kiter who moves around the planet should be constantly aware and check and if necessary strecth/adjust any differences that build up. This regardless of brand.
Attached is a pic of Core dealers recieving instruction from the line manufacturer on correcting length differences by stretching individually on a bar randomly selected from the beach.
This is even more confusing.. if temperature was a major factor you would see different performance of the kite after you dunk your lines in cold water...
why would a temperature change affect lines that are about the same length and width differently?
Some experts in this article seem to agree with my previous statement, blaming it mostly on stuff that gets in between fibers with time.

Now your screenshot shows calibration w/o pigtails.. so if this is official recommendation from CORE, I'd go with it..
Just checked with my 2 bars, and if you leave pigtails on, and calibrate with my method, the difference in lengths would be less than a centimeter as opposed to the method above.
Probably not enough to notice the difference, I never did.
