One correction related to attribute increase by act parts:

the formula is more complicated. +1 per two act parts only works approximately for base value 5, and not in all cases. I tried hard to find out the exact formula but sometimes there are single deviations that don't fit. I even don't know if results get rounded or not.

This may give an orientation, until I know more or someone has more accurate numbers (results must be rounded to fit):

Part 3: base value x1,15
Part 6: x1,45
Part 12: x2
Part 24: x3

Another correction: I use Notepad, not Wordpad of course.

And as reminder: If you don't have the xlsm and txt files in your folders (it seems they use to get downloaded along with the Editor and didn't come with a patch) Cadmus88 from Larian has offered a link to download them manually:

To generate txt files from xlsm files you don't have to generate all. Cadmus88 shows how to do that some posts above.

Since editing long posts is not possible I tell you the changes here. As soon as I know more about the mathematic logic of act parts I'll ask Raze to update my guide.
