With all the talk in this thread, lot of it quite vague and rather marketing like, this picture from Roger is the best and most clear demonstration of what a -20deg IAT offset really does!

I was always little annoyed that none of the various IAT offset device vendors on this forum never provided a plot like this.
Actually showing what their product does.
Instead everyone resorted to providing a lengthy verbal infomercial.
