Just one comment - point nr 2 does not make sense :
Short depower(hardcore riding) Aprox. 3+ kite quiver
Medium depower(balanced) Aprox. 2-3 kite quiver
Long depower(SLE/BOW like) Aprox. 1-2 kite quiver
You can design a short depower and a 1-2 kite quiver.
You can also design a long depower and having a 2-3 kite quiver.
In other words: depower distance and depower are not the same thing !
Newer SLE's dont have long depower - some has really short depower, but the same or more depower range as earlier, giving you a 1-2 kite quiver.
The same will apply for C kites, depending on the design.
So the correct questions could be something like (where all 3 are good and used choices today) :
Do you want a short depower and big range ?
Or do you want a longer/balanced depower and medium range ?
Or do you want a short depower and short range ?
On top of that, comes bar pressure as a choice - and depower range and bar pressure is not proportional - it depends on design once again
And NO, short depower and big range is not always the best, as it is like driving a formula1 car - very difficult because the gaz pedal is too sensitive for most
A balanced ratio is much easier to use, and will in most cases perform better especially in chop or small waves when you are hooked in the CL.
And way easier to adjust the trim when unhooking
I am just saying that there is so much more to this parameter than at first glance !
On some "older" kites, depower length and bar pressure and depower range are connected very "simple". But on modern kitedesigns, there are more to it
