Depend on the age of the kite. F18 rule of thumb used to be you could grab the luff with your fist and turn it 90 degrees.
Not anymore. Most carry it tighter than that now.
Agreed - we started running our N20 tighter than that based on the F18 experience.
The luff of the kite in that picture is far too loose. It needs to be at ~least~ where you grab the luff with a fist and turn 90 degrees. That luff looks like you could do that with about a fore-arm length of luff.
