Well, the biggest kiteloop i've ever seen was from Ruben in hurricane conditions off of a wave, and it was about 65% of his line length, which made it about 60 feet high.

In this photo Billy seems to be 1.4 times his line length high. Thats over 100 feet... closer to 120 feet. 120 feet is a big number for a jump on flat water.

I think they got the photos mixed up.
