If it looks good to you, it should work fine during your trip. The point is that you are tailoring your
own lenses to your
own camera body.
Every camera body and every lens is slightly different, and in certain focus situations they need to be "corrected" to be perfectly sharp. My various lenses have had everything from "0" to "-10" on the focus chart, but on any other K20D the settings would be different based on where the sensor plane happens to be on that body. Put a different 16-50 on your camera and your previous adjustments wouldn't apply - that's why they are stored in the body, based on the serial # of the lens (I think).
Have a great trip, and Happy New Year!
BTW: if you are really anal(ytic) about setting your per-lens AF adjustments, you should use a tripod, 2 sec delay, and overcast sunlight.
