where can I find a coast-down spreadsheet?
OK, back in the old days (yes, I'm old. I remember slide rules and FORTRAN and the excitement of a Texas Instruments SR-51. In fact, I think I might still have mine.) I remember there were calculations based on timing coast downs that would allow you to calculate both rolling resistance and aero resistance. I've seen mention of that being done by Excel spreadsheet (ain't computers wunnerful?) and am wondering if there is a spreadsheet readily available since my brain hasn't done that kind of physics calculation for, well, a long time. Anybody?
