That is a nice plugin. It installs easily. Works as advertised.
And for posterity, I noticed that my mouse movements are pixel perfect at the 100% zoom level. At the 200% zoom level, the mouse moves in increments of .5. The strange coordinates appear when at some arbitrary zoom level. It is much easier to hit a full pixel when the mouse is moving in increments of .5. I'm now zooming in 100% 200% or 400% and it is easier to stay pixel perfect.

Alan,
I understand what you mean by "pixel perfect". But also for posterity, keep in mind that a pixel is not a little square:

The paper you linked me to is entitled "A Pixel Is Not A Little Square, A Pixel Is Not A Little Square, A Pixel Is Not A Little Square!" It is easy to imagine the author saying this while throwing this dinner plate up against the wall. Please, don't mention pixels around Alvy, we don't want a repeat of last Christmas.
I am programmer and I've learned to be incurious when someone tells me "You Are All Wrong, You Are All Wrong, You Are All Wrong!" Even when the person is right, they are usually right in a way that is hard to understand.
More often, they are quibbling. When they say, "I know what you mean, but you're wrong." it usually translates to, "I know what you mean, but that is an abstraction." Computers are a world of "there's more to it than that."
I understand that a pixel is an abstraction. For me, it is suitable abstraction. A pixel is a little square that can hold one color, is enough of an understanding for me to create web graphics that do not unnecessarily dither. (PixelSnap described the problem perfectly.)
I really don't want to put an understanding of monitors before an understanding of, say, the rectangle tool. I have so much to learn about Inkscape already. All I want to do is create web graphics that don't unnecessarily dither, which I am now able to do.
