These data appear correct, but do not allow us to directly conclude on the respective measured effectiveness of power kites (paragliders) compared to parachutes, in yo-yo mode for power generation where tethered kites are implemented instead of free parachutes and gliders, leading to a different behavior.
Indeed other factors come: crosswind power kites face the “stop and go” (due to power variations within the flight window) drastically reducing the power produced, for an efficiency ratio that I have roughly estimated at 3 (power kite) to 1 (parachute) per surface area unit, comparing a power kite to a parachute kite of the same surface area.
This small difference could perhaps be corroborated by figure 15 which indicates 12 m/s wind speed at mast height while the text suggests much higher wind speeds at kite height, and also (in a lesser extent) to the Chinese parachute-based AWES compared to flexible crosswind kites like SkySails (figure 15 linked above) or Mutiny.
I do not think the difference is significant enough to justify the land and space use required by the crosswind power kite, as well as a complex control system, and greater fabric wear due to higher stresses.
