Ok, after a lot of bickering and over complication, I am going to hope to help simplify this serve. When I would try the "7 to 1" kick serve, my CONTACT POINT of the serve would always be TOO HIGH. This caused the ball to go, well, 3 feet, 6 feet, maybe even farther past the service line! It sucked.
As my best serve was always my first serve or flat serve, my brain always wants to hit the ball at its HIGHEST POINT at extension for power and to get it over the net.
So, this is why I picked this serve up soo easily. I can now have that same high contact point, but now hit another variation with nasty spin!
For those who have nice kick serves. Well, keep them. Your contact point is much lower, your toss is much more "above your head", and surely your back is more arched. I, at 6' 2" tall, am doing this all by tossing at nearly my same 1 foot in front, 1 foot to the right flat serve spot(and my back has next to no arch), yet my racket path follow through is more down and around, as in Pats 11 to 4 visualization (vs. my flat serve that pronates forward torwards the net first and then ends down to my left side)
Jeff Salzenstein shows and exaggerates this around the body follow through on what he is calling a slice serve:

If you take away the tricky "11 to 4" thing, and simply watch Pat or Jeff(or many touring pros second serve swing paths) you will notice that is where Pat got his "11 to 4"(I always hated this ball as a clock thing, as it makes you think in a 2d plane, while all swings are in a 3d plane, which Pat does show and tries to convey)
Oh, and lastly, swing fast, swing very, very fast. If not the ball won't have enough spin to bring it down into the court and float on you (Did this to me the first 4 plus serves playing doubles yesterday) until i got mad and just swung faster and then it was money all day!
Good luck.
