As an Optician for over 25 years it is in my nature to measure and calculate on a daily basis......
Patients center pupils positions....frames sizes...optical lenses powers,curves,thicknesses etc....
So today it has been 13 years 3 months that i started kiting (Feb 25 1999)
And i have some interesting numbers (i think)
To be conservative let's say on a 30 day month i kited 15 days /month since beginning
And i go out on average for 1.5 hrs at the time
With lines always "on" i can get on the water 3 minutes faster than anyone with lines "off"
It's in your nature to measure and calculate? But you say, "...let's say ..."? Don't you know? Don't you keep records? Any attempt to estimate your kiting figures will be outrageously wrong. People kite far less than they think they do.
BTW. I prefer to disconnect. I like to wash my bar and lines in fresh water after every use. I have a bar for each kite to a) spread the wear, b) ensure that I have a bar and kite in each bag, c) as backup, and d) allows different tuning options. Small kite with a long bar is joyous.
I use a simplified version of the Brett Lickle method. http://www.youtube.com/watch?v=9_FxYkg1vZc
It's simplified because I don't bother with keeping the ends managed so I can connect. I just link them together and wrap up. Linking the ends avoids those annoying little tangles with the pig tails. Not being too neat avoids all the stuffing around of being too neat.
Even leaving your bar attached you still have to check the lines at each end. If you don't check the lines then you're a dangerous fool. Your actual saving would be no more than 30 seconds on each setup (I estimate
