Interesting ideas. I use spreadsheets for some crude manual forecasting, but I hadn't thought of generating reports like that. That would give you a lot of data to identify the pain points.
Outside of raw numbers though, I wonder how to get feedback on content and design. For my previous game, I was able to get a good bit of feedback to improve the early game, but relatively little beyond that. And that's fair enough, because 30m of peoples' time is already a lot to ask for, but it does leave me uncertain about what (if anything) I'm doing well and what needs to improve.
