I think its pretty much a preferential thing Mike. Pure summing is best for noise reduction, but quickly exceeds the tonal range, average is next best for noise but if you have a satellite or meteor in one shot you will have to exclude that shot or you will still have the streak. Median is best in that scenario but the noise reduction isn't as good as the other two.
