The elevator ride? 1st floor, women's lingerie; 2nd floor, men's socks... 10th floor, brown shorts!
Hit by a gust or wind gradient... if the kite is above you and you're not moving it.
If you redirect or loop on the way down, the kite's movement generates apparent wind and you get the lift from that - especially as it goes over the zenith, but unless you're proper kite-looping it'll be more of a hover, than a lift...
Gradient effect is very minimal <50m.
You can get a nice gradient in the even just before sunset bcos of the cooler air... best time to boost big.
