My understanding may be wrong and I welcome you to correct it.
I paste the bridle of Reo as an example of a non pulley kite.
1) For pulley less kites only one of the A1,A2,A3,A4 carries the load of the front lines (the rest have a very small load that just keeps the shape of the kite)
A1 (and the back lines) is carry the load at the maximum sheet in and A4 carries the load when fully de-powered.
2) A bridle with pulleys, because it can move it divides the load in the bridle lines.
My though is that a bridle with pulleys is less sensitive to stretch/shrinking exactly because the pulley can move and redistribute the load. That is that even if +/- a bit it would still work better than a pulley less bridle.
Is this thinking correct? If not, what's wrong?
Your thinking is correct. But...
But you have to consider "hidden" parameters when you compare kite features.
The top for Ave Joe are "personal feeling and fun factor" which is very tricky to determine as it difficult to quantify, and its almost impossible to carry out statistical testing under controlled conditions.
Even if you would like to check by yourself, you"ll have to carry the test with same kite and two different bridles (with and w/o pulleys), right?
Back to your question, the angle between the front lines and the leading edge cord (segment between front tips) determines the "loosness" of bridal segments.
By chance, just a couple of days ago I was wondering about the same question and I played with the front line to see which and when the bridle segments get loose.
I concluded that for practical riding the angle variation is relative small and most of the time all bridle segments are under tension (more or less).
So in theory you are correct, but practically it has a less significant impact on stretching than in steer feeling (if those two can be compared
