Your electric pump seems slow at shooting air in the kite to be able to do all that stuff
In your best estimate what amount of time would your electric device take to say pump a 19m2 ?
What % faster would you say electricity is to get to the PSI needed in a kite ? 50%..30%..20%
Do you have any electric time numbers for say pumping a 12 or a 17 if you use a kite that big ?
Muscular time (actually quite easy) for my 19 is @ 1 min. 20 sec...........for my 12 @1 min.
Do you have a video in real time ? I do not think you realize the actual time you actually use.
Do it with the "largest kite you own" and self launch yourself on land in 8-9 knots wind
If you can beat ...harness on..shades on...pump kite..lines on..launch in less than @ 4 min. 30 sec.

I see guys like you all the time with one bar.............several kites
They are on the water..wind picks up..they come in to change kite and have to take lines off ..
....then put them on their smaller kite.....quite a time consuming project and the wind is blowing !!!
Me i go to car ...get my smaller kite with lines on..pump it..launch...tear up the waves......
....while i watch from the water people still rigging....not even close to launching their kites
