I certainly wouldn't worry about dropping the base SOI map due to ICP changes.
I'm stupid-conservative when it comes to my SOI. I smooth out the map and give it a nice, flowing look which will raise the map ever-so slightly right in the center but lowers it a little in others......just so it looks like a smooth, rolling wave. As far as values go, none of them are changed more than 2 degrees in either direction.
