Having bought one of these chinese hydrofoils (aspect ratio=6) i was planning to build a more begginer friendly set of wings . But before starting the construction, i did some quick math and found that the difference in the lift slope between a high and low (3.5?) AR wing is at most 20%. in other words, when you change the angle 1 degree, the lift of the high ar would go up 20% more (at most!) than the low AR one.
I was expecting a really big difference. My guess was that low ar wings were less sensitive to changes in the angle of attack and hence easier to control, but <20% doesnt seem like a huge improvement. So, my question is, what am i missing? What makes learning foils begginer-friendly?

This one has an AR of 4.32 which is perfectly within the range you recommended and with 700cm2 it's bigger than average
