It's fair to say that it will not be 100% accurate unless a large group of people have contributed to each species, even if the program does warn of compatibility issues
No matter how experienced the person behind the program, it's highly un-likely that they or someone in their first-hand experience will have tried every combination on the lists. This means some assumptions have to be made unless you have a larger than practical number of people behind your project. The fact that you the writer, or your helpers, will have made assumptions means there is likely to be errors unless you and/or your helpers have a perfect ability to predict the behaviour of living animals. This means that, while a useful tool, your tool is just that. It cannot be a substitute for asking real fife people for real life experiences with real life stockings, as it's theoretically compiled based on one or a few people opinions of what works. No doubt your program is very good at what it does (your right, I haven't looked at it, mainly as I cannot work out how your supposed to open it without reading that page in detail {I skim read parts of it before getting bored and moving off}) but no program of this nature is ever going to be 100% error free
Stocking is one of, if not the most complex part of a tank if your going communal IMO. While I like to think I know what I'm doing with stockings, I also know I don't know all of it and regularly find myself having to ask others myself, particularly if odd-balls are concerned
Having tried Fighters and Tiger Barbs back in the days when I was starting out in tropicals though, and knowing of a few others that have also tried it, I'd suggest you change your spreadsheets answer on that one to highly un-recommended (or it's words to that effect) as it is a very messy one IME
All the best
