Yeah I was going to say that CCDstack must do that automatically as there is no combine option of weighted sum.
Median combine is the usual choice as it gets rid of outliers better than the other methods. Sum can be useful in some faint nebula type shots.
My go-to combine is median. If you have enough subs you can see the flaws disappear like satellites etc.
I also do normalising then hot and cold pixel rejection as a standard action also. It gets rid of the inevitable coloured dots that often appear without doing that step.
