Spreadsheets are non-linear. I would rather be given the chance to explore first on my own, and then have a chance to ask questions. The forced walk-through might be helpful to some people, but that can also be documented in the spreadsheet. Also, formulas are what they are. You can try to tell me what they do, but the formula speaks the truth and I don't want noise when reading formulas for the first time. Again, you can comment any non-obvious formula, but let me read the formula on my own.
