Is anybody willing to write & post their procedure for post-processing, specifically stretching?

I've got a good handle on the batch commands, but the function and workflow order for the all the sliders on the right side of the screen mystify me a bit.  I'm sure I'm not alone.

Any experts out there willing to take on this job, to help others?

I find that APP does such a good job of auto stretching that I just export the final image in 16 bit TIFF and then use Lightroom to finish it off. However, you can play with the sliders you see on the right hand side for more control. Did you see the red box with the ? in it. If you click on that it will give you a lot of help on the sliders. Maybe when I have a high quality set of subs, I'll spend more time on that last stage. Clear skies!
