I didn't have any problem with meter placement. Though if you're using the new i1 Display 3, Tom Huffman (developer of ChromaSoft) says it should be tilted on the horizontal plane instead of the vertical one.
The one thing that I noticed that had the most effect on my calibrating was contrast and brightness. Those have to be correct. I used the flashing bar patterns from AVS test pattern disc.
Make sure you turn off "Epson Super White." It sounds like a good thing, but really what it does is clip the Whiter than White (WtW) and Blacker than Black (BtB) from the signal. It also makes it impossible to set brightness and contrast well because it seems to have to side effects on the rest of the signal. If it's on, you won't get any flashing in the WtW and BtB areas. When I had it on, I couldn't find a good setting with Brightness and Contrast that allowed both the whites to be bright and the blacks to be dark at the same time.
I'm going to calibrate again tonight (or maybe later this week) after bumping up the gamma from 2.2 to 2.4 to see if I can get closer to 2.2 (as suggested by Michael TLV, above). You may notice in my report that the gamma is around 1.9~2.0, even though it set to 2.2. You may have to do the same.
Also, I know some people use the full screen patterns on projectors because they don't have the power problems that plasma and lcds have when using them, but I still used the window patterns. I did this because my room does have some light bounce issues and my walls are red. I didn't want the meter to read any extra red from wall reflections on the bright full screen patterns.
Now as for the color patterns, I have read some folks recommend using the 75% Saturation CIE patterns when doing their readings, but I couldn't get good results this way so I stuck with the 100% saturation.
Hope that helps!
