> but is excel speed a common problem for people? Anyone who sets excel to "manual calculation" mode to avoid pauses whenever they make a change in a big spreadsheet might be interested in this. If this engine removes the need for that, it could be a pretty big deal. It'll definitely make things easier for me when I'm messing with material testing data. But like you said, how do you market it? How do you reach the people who need it? I suspect that for most people excel is just a tool, and they're not involved in excel communities or excel culture (if such things exist) in a way that would allow them to discover something like this.
