Does Autostakkert really run the surface stabilization step twice?

When using Surface image stabilization, Autostakkert appears to run the Surface Stabilization and Buffering and Analysis steps twice. First, when you Analyze, which you are forced to do before you can place alignment points, and again once you click Stack.

 

Is it really doing those steps twice? If so that might be a legitimate reason to pre-process in PIPP. SS and B&A take 56 minutes on one of my 120 GB lunar SERs, on my 32 core workstation with 256 GB of RAM. If it's doing it twice, which it certainly appears to be, that's kind of absurd.

I do not know for certain, but I suspect the first round is to align the image globally, and the second round is to align, or at least locate, the anchor points.

 

Planetary System Stacker actually shows statistics for how far off the anchor points are in your images. This gives you an idea about how bad the seeing was for the set off images you selected to stack.
