As Graeme indicated elsewhere in this thread, you might try filtering out gamut 
extremes, especially if it's just for some small spikes that are hopeless 
anyway. I haven't had to play around with that, but it sounds like the problem 
you're experiencing.

Graeme, might there be some way to add an option or some other tweak to 
automatically ignore outliers beyond a certain standard deviation, or the like? 
Manually figuring out what parts of the gamut to ignore can be a challenge, and 
I rather suspect that some sort of programmatic smoothing is going to do a 
better job than most of us humans would anyway.
