Great anecdotal evidence Mark, thats what I'm talking about! Same
fuel burn, double the climb. The key of course is that less work
(useless work) is being done because your kite has less mass. You're
moving the same payload, just less airplane. I'm sure you can land
way slower at the end of the day.
