The answer to the first question tends to agree with your idea. However, AI asks for more specific information several times and when given enough information the answers change accordingly. That’s part of what makes the lengthy dialogue interesting.

The point stands that the line of sight from the Prayer Man position to the limousine is blocked by the west wall of the portal...This is evidence that Prayer Man is Stanton since she said she couldn't see the limousine at the time of the shots...

Of course I remember, Pinko.
This is the lie...sorry, fabrication... I'm talking about, so obviously I remember.
I've argued all along that Shelley immediately ran from the steps and met Gloria coming the other way. He states this in his affidavit. (People such as yourself have to ignore the fact that, during his WC testimony, Shelley completely changes his story, stating that he stayed on the steps for at least 3 minutes before Gloria ran up).
The 'fabrication' I have to keep calling you out on is the part where Shelley calls Lovelady to join him. You've invented that. It's your fabrication. It is not based on any testimonial evidence whatsoever. It's a lie you have to tell because you can't find any other way of getting Lovelady and Shelley on to the Elm Street Ext. within 25 seconds.
You have swallowed down Kamp's 'Lovelady' image without question even though it has been demonstrated that this image is dubious, to say the least, and now it's been pointed out that it's physically impossible for Shelley and Lovelady to do what they attested to in their WC testimonies AND be on Elm St within 25 seconds, you've had to invent this lie. If it's any comfort, Lance "I think I've Had An Accident" Payette did exactly the same thing.

On the other hand, my own identification of Lovelady in Darnell does not require me to lie my way through an explanation and makes perfect sense with the known timings:

My first reaction before reading the in depth analysis is that tracking is the preferred method. The reason I say that is because aiming at a fixed point and firing as the target crosses that fixed point is going to encourage pulling the trigger rather than a steady squeeze of the trigger. I was taught not to force the gun to fire but squeeze and let it fire when the proper trigger pressure is reached. Pulling the trigger tends to cause a shot low and to the right for a right handed shooter.

I'm sure there are highly skilled shooters who can use the other methods, but for most shooters, tracking the target while putting a slow squeeze on the trigger is going to produce the best results.
