I'm not a scientist or anything. Well sort of, amateur like, but I've pretty much learned it all through my interests in brewing, baking, etc., not formally. I'm curious. When the software doesn't work for me, I try to work it out for myself. The same kind of impulse that makes me brew, bake, tinker, whatever, in the first place. Basically poking stuff with a stick to see what happens. Maybe smarter people can use my contribution of data and build on it.
