Well, so that's what I am saying. That's how paintbrush tool works. If 
you draw in between 2 pixels, it will just draw on both pixels because… 
well you can't draw in-between 2 pixels (or like drawing 2 half pixels)! 
That's the nature of pixels of being the smallest non-breakable elements 
in a raster image, as I said (there is no half-pixel concept).
The paintbrush is this kind of tool where it interpolates, and that 
allows smooth-looking lines from afar. But that's indeed not ideal if 
you want to work on pixel precision.

For what the first email originally asked for, the "pencil" tool is more 
adapted: it draws always on 1 pixel (for a 1-pixel brush). So that's 
quite adapted to the request. And your screenshot shows it well. But 
from afar, that can make some harsh lines (as soon as you do diagonal or 
non-straight lines, you'd see it).

That's just 2 different tools for 2 different use cases.
In any case, as a conclusion, yes it is possible to work on pixel 
precision, and for this, pencil is probably the best choice. Your 
screenshot agrees with me IMO. :-)

P.S.: it is actually possible with the paintbrush to do 1px lines, just 
as for pencil. But you'd have to click exactly in the middle of a pixel. 
Of course, that's just for being picky, I'm not saying that's a friendly 
usage. :P
Just use pencil when you want to make sure you draw only exactly a 
single pixel, and that's it!
