Can you perhaps consider editing / supplementing the first posting with the various recommendations and tips that have come up in the forum since your excellent first port over a year ago ?
I have now got lost as to what is true best practise using your LCD chart...
In post #68, Nicolas Claris already made a nice summary. Otherwise it's simple for most to use it. Just make sure you display the target at a 100% zoom setting (true size), otherwise it will be hard to get the moiré showing. I suggest to calibrate at the most commonly used shooting distance if possible, because there may be differences between close and far focusing.
The easiest way of determining the amount and direction of offset to be corrected for, depends on the lens model. The ones with an internal focussing mechanism won't show a focus ring rotation, so you'll have to pay close attention to either the lens window with the focus distance indicator, or just note which direction you need to turn the focus ring after AF to achieve maximum moiré.
In general I find it easy to focus manually with Live View and then check which direction the AF thinks is better, then correct until Manual and Autofocus agree. However, when the AF is a bit twitchy before it settles, it may be easier to first AF and then use Live View and note which manual focus offset direction improves the visibility of Moiré. Either way, after adjustment there should on average be no substantial bias towards front- or back-focus anymore. There can still be some variability around the optimal AF setting, but that's normal for the phase based AF-technology. AF is not 100% accurate and repeatable, but on average it's very good.
Just remember, you are trying to reduce the bias in focus offset between AF and manual Live View. Whatever method works for you to achieve that goal, is the best one. Also, don't worry about damaging anything, you won't, and you can always get back to zero adjustment for an out-of-the-box situation.
A final note. I have no personal experience with the newest contrast based type of Live View, so I have not described a procedure to exploit that, if possible. It will probably allow you to see the maximum moiré that can be achieved when it is of the small, mottled, kind (don't know what happens with the color band kind). However, I suspect that it is still easier to check the offset by manually rotating the focus ring in Live View after initial AF (that will give instant feedback as to the direction of the correction needed).
