You said:

" You get an indication of how consistent the frame sharpness is is by

looking at the Min - Max value range, the STD68 or STD96 standard

deviation values and how skewed the curve is. The larger the Min -

Max range, the more variance in frame sharpness and the higher you

want to increase the Confidence Interval Slider"

Then, what would be an acceptable range of values for STD68 and STD96?

We give a approximate value for each case in the Astro IIDC Manual on pages 32 to 33.

Smaller is always better.
