No one person will have the perfect answer, but the more you talk with folks about the assumptions they make, the easier it will be for you to hone in on what assumptions you're comfortable using to run your numbers.To make all this a bit more concrete, here's an example of some numbers I ran just this morning on a small MF buy-and-hold (which is the focus of my investing).
