Model + aspect class
High-aspect / big-air designs, freeride hybrids and lower-aspect kites can create different lift, depower and turning behaviour. BTE records the actual model rather than treating every 10 m kite as equivalent.
BIG AIR · SETUP
SETUP SCIENCE.
Kite, line and harness choices matter. The challenge is separating convention from what actually improves your jumps.
EQUIPMENT CONTEXT
SETUP CHANGES THE OPPORTUNITY — BUT BTE DOES NOT INVENT THE EFFECT.
Kite architecture, size, lines, harness and board are first-class context. Generic conventions inform the explanation; your own repeated evidence decides whether they earn a numerical personal coefficient.
Line length
Longer lines alter the flight window and timing; shorter lines can make the kite more immediate. BTE records line length, but only learns a height effect once there is enough personal contrast.
Seat / low hook
Your seat harness is part of the setup record. A lower hook can affect edge retention and body geometry, but BTE does not assign an automatic height bonus.
Speed + edge platform
Board dimensions, rocker and stiffness affect approach speed, grip and release. The board belongs in comparable-session filtering even when the sample is too small for a standalone coefficient.
Best setup
The best setup call should come from your own matched sessions: similar wind and geometry, different kite/setup, enough repetitions, and a confidence label.
No folklore coefficient
Aspect ratio, line length and harness are plausible performance factors. They only become numerical BTE effects when your data shows a repeatable difference after conditions are controlled.
