You can't really use math to calculate the dimensions of the viewer by calculating scroll bar/bottom bar and dpi sizes, it does something else. Your best bet is to get ballpark with dpi, and then make a 40 page file or so with incremental .01 inch crops and slowly go from there. You'll get it eventually. That's what I did for the DX anyways, and that's what I got for my numbers. They seem to work well. Not having a K2/K3 anymore, I can't say what they are for that device.

I don't understand what you mean.
The Kindle screen has certain physical properties in terms of size and dot pitch, and its software places the PDF image in a fixed location on that screen. Deriving the proper dimensions to use in setting up a Kindle-targeted document's page size is not a matter of calculation, but of observation and measurement - just as if one needed to lay out a document to print on a non standard paper size. That's what we have done here.
If the goal is to have the text size that's displayed on your computer display physically match the size of the text on the Kindle display, then you would need to fudge the dimensions of the page size, because even when documents are displayed at '100%' or 'actual size', it is in general not an accurate reproduction of the size when the document is printed, or as in this case, displayed on Kindle.
If you're saying that the mapping from the page layout application's representation to the PDF file's representation to the PDF viewer's representation introduces some distortion or inaccuracy that can only be compensated for by trial and error, that's another matter. But since PDF is supposed to eliminate that possibility, I would want to know more about what you are seeing.
For example, I have seen more or less random instances where fit-to-screen fails to perform as advertised, and clips off the bottom of the PDF image (which is nevertheless always shown in other zoom modes). This may turn out to be something that requires a workaround of some sort when producing PDF documents for Kindle.
