...think about "standard settings" each of us should use so that the data and the curves can be compared easily. Maybe even some template, excel or something, where we can bring our measurements in to?
Some fields would be needed to be filled in: time, date, location, equipment, author, comments, ....
Does that make sense to you? It would be better to have that at the beginning before everyone has 50 files but comparing the files to those of other people becomes unnecessarily hard due to small incompatibilities.
Wow, having 50 raw spin-decay curves (SDCs) to analyze and compare -- beyond my wildest dreams!
Ideally, we'd use Excel files to share the raw (time,speed) data so that anyone could analyze it.
Personally, I'd find the following useful:
1. Experimenter's name
2. Date data was acquired. Time if necessary.
3. Name of top.
4. Enough low-res photos of top to show its shape and aerodynamic properties.
5. Top description, including any noteworthy features not clear from photos.
6. Pertinent top dimensions, with reference to photos as needed for clarity.
7. Known or estimated mass properties, including mass, CM height, and moments of inertia if known.
8. Tip details, including material and estimated radius of curvature over contact patch.
9. Plot of raw SDC in RPM vs.
seconds.
I'd really like the graph to include an exponential fit -- including the associated decay constant or lifetime and R² goodness of fit. I think we'll learn a lot from seeing how much the measured SDCs differ from their best exponential fits.
Finally, would love for all data other than speed (in RPM) to be in meters, kilograms, and seconds for direct comparison and easy analysis without conversions.
Likelihood of getting even half of that wish list = zero, but a template might help.
