I learned about the effect of the in-camera pushing/pulling base iso's years ago when I still had a 40D. This was particularly interesting in the high iso range because it taught me I might as well use iso 1250 instead of iso 1000 when I needed sufficient shutter speed. And iso160 became my base iso except when I required longer shutter speeds. With my current camera bodies I don't worry about this anymore.
