Goodbye Noise! Even Better Stacking.

The image stacking statistics feature in Photoshop Extended is great and could be even better with some minor additions. Professional statisticians sometimes use the "trimmed mean" rather than the median. This is an average that excludes a percentage of the most extreme pixel values - say the top and bottom 10%. It can sometimes be more effective at noise reduction than either the median or the mean.
A simple extension of this idea would be a trimmed summation.
