As a begginer my instructor has the kites ready for me, 2 sizes at least.so, it takes me no time at all to rig ( but takes me a lot to start riding)
Many times i will rig / pump our 2 Light wind kites
My wife goes first on her 17
4 min 6 sec off the ground...includes pumping 78 sec ( 5 seconds less than the 19m)
Now if i pump a 10 or an 8 the time i save is mostly at pumping (@ 20-25 seconds less than 19m)
But when there is more wind the time saved pumping is used making sure all is positioned perfect
Higher winds means the launch becomes more dangerous
So the time stays about the same large kites quick inflation vs medium size kites
I would definitely say that when i rig a 6 or 5 in high wind gusty conditions and self launch....
.....the time saved at pumping (@ 40-45 seconds less than 19m)...
.....does not count anymore at going fast..
....because i really really triple check everything and must
launch perfect the first time
So in 6 or 5m2 conditions i take probably 3 more minutes than with my 19 for extra safety reasons
I would say that the windier it is the longer i chose to take
So to me smaller kites take more time to get off the ground 99.99% safe
Nothing is 100% safe...always be ready to eject
