The wind is a source of energy. It can always add height if there is more wind during your jump.

And the loop could (not saying it always is) maximize the use of the wind to get lift.
for the original author of this topic look how when he loops three times at 2.30 he is not fishpoling the bar or having the bar all the way pulled in... otherwise he would fall faster like what you are experiencing.

We normally never go downwind at the exact same speed as the air (usually we only do that immediately after a kiteloop), so you can use theoretically use this energy to make height (though we don't do it in practice). Our wings are so inefficient compared to aircraft wings that most of our lift is produced quite near our take off when we jump so aren't normally able to harvest this kinetic energy. I can imagine a very efficient wing, some paraglider wing for instance, that lifts lightly off the water from a dead stop and continues to glide up for quite a while.
I agree of course that there is a fixed amount of total energy available when you jump you can't make something out of nothing and you can't increase it while in the air.

Also, think in three dimensions. Presumably there can be a vertical component to the gust. Watch a seagull hover.
