Both Tom Huffman's Guide to Color Calibration and the Grayscale and Color Calibration for Dummies Guide show no preference for either 75% or 100%, only that one uses a matching % for the white window.

It's simple logic... if you have only ONE adjustment point, would you be more likely to get better results at either end of the luminance scale (black or white) or in the middle of the luminance scale (a 75% window is about 50% stimulus). And yes, if you use 75% color windows you MUST use 75% white for the reference also.

That said, there may be cases where you want to use 100% or 50% windows because of a response problem or a very specific issue that needs to be fixed at one part of the luminance scale (but the display is fine at other steps along the luminance scale.

You have to keep your wits about you. But most of the time for most displays, especially plasmas, using the 75% windows will produce the best overall results. But there will always be the exception to the rule here or there - you just don't want to miss those because you get into a habit of doing it one way to the point that you forget to check what's going on with the display at several luminance levels.
