Looking good Dave
IMO it is about the same.
If low wind and you need to pump, and dropping in the lulls, and if you are on the lower end you might also lose your foil (drop down) when you jibe.
Meaning more work to get up foiling again, and you have to "wait" for wind, which is not tiresome, but boring thus mentally exhausting.
So a bit harder than "smooth perfect" wind.
And opposite, when in the upper end with a 3 or 4 m2 wing, all above is easy, and transitions too, even with small mistakes, and handling the wing is supereasy as no size and you dont get backwinded in jibes either.
But you will also have chop wind waves now, or somewhat bigger waves - meaning when you transition in this, you gotta be way more focused, and you will ventilate or make another error sooner or later, in this chop mess.
Besides as you say, usually more gusty wind in the upper end - but amazingly it does not mean much for the average rider - a lot easier than with a kite.
This concentration, and harder crashes, also means it is more exhausting than in sweetspot wind.
So I would say same same, too light wind versus the small wing size wind.
