A couple of people have mentioned using printed pages as test targets for their K10D and K20D focus adjustments. They may be misleading targets.
The central focus area is the size of the spot metering circle--MUCH larger than the little red square that lights up. If there is more than one item of detail in that circle, it seems to be random which one the AF locks on to. So, if one is focusing on a page of text, and more than one line is within the spot metering circle, you may get misleading results. Focusing on a ruler, which is certain to have several markings within the circle, is even worse. I strongly recommend using the focus test chart here: http://focustestchart.com/chart.html Note that it has a single bar to focus on, with the calibration scales off to the sides where they won't confuse the AF system. It may save lots of time and aggravation.
