Fill with edel basic settings  and see where %  are  positive or negative .

This does the same basic thing but you have to use your brain a little more.   :-) I originally did these in Excel and, as you say, they can't be uploaded in that format.  So I converted them to jpg formats and uploaded them that way.  They're as easy to use but don't show all the math.  :-)

I uploaded these in their "native" Excel formats to my Google drive.  There are several sheets within the workbook, which are accessible using the tabs at the bottom, and instructions for use pasted on each of the sheets.  The sheet that comes up first has all of the different combinations for all of the carb variations.  There are two large tables on the first sheet.  The left one is sorted by "cruise" and the right one is sorted by "power".
