The question is simple: how much?
The answer is not much more complex - it is variable - depending on body weight, style, and if you crash the kite.
And yes, wear starts instantly when you pull the kite out for the first time. The wear curve is also variable and considers factors such as loading, care for the lines, particulate matter such as sand or suspended minerals in the water, and many other factors.

Ffs I am not talking about degradation, what this has to do with line strength ?
People answered and you are not accepting the fact:
- it is possible to use super thin back lines.
How thin? We don’t know simply coz we don’t know how much we pulling.
Yes, we do how thin. Look at the Mutiny kiteboarding video. Size your lines to exactly the max shown on the gauges, and they may not break. But they will break on a crash, or a gust, or with a heavier rider, or while unhooking.
You can take the advice of a respected manufacture (Flysurfer) and use 160kg back lines, so long as you don't jump. Or Ozone's at 200kg with regular (100hr) replacement.
Again, not trying to berate you or put you down in any way, but do you get the concept of multiple variables in an equation?
The answer, in its simplest form, to your origional question, is "There are multiple variables".
