Serve: How much of the shoulder coil occurs prior to release of the toss?

[Raul_SJ]

How much of the shoulder coil should occur after the toss is released, vs before?

I am using the platform stance and Federer type tossing motion. If I align the back foot more or less evenly with the front foot (Pic #1 below), I do not generate much coil. The only way I am able to comfortably generate coil is to continue rotating AFTER the toss is released. And that feels awkward to me.

I tried experimenting with sliding the back foot toe behind the front foot as in the Jeff Salzenstein #2 pic below:

#1 Back foot toe aligned with mid front foot. ___ #2 Back foot toe slid back behind front foot​

The above #2 stance feels more comfortable as the coil mostly occurs BEFORE the toss is released... Still experimenting with these two stances... I would prefer #1, but it is difficult to for me to generate the coil with the feet-evenly-aligned stance.

All experiments like that are done using a radar gun
If number 1 provides higher speeds one should go with number 1

I do not promote the platform stance

Nor do you promote the use of video as example. Jeff has a nice serve though, as witnessed on his video's.
