Ooooh, data!
4.3 mm is a tight gap. I think most companies are shooting for 4.5 mm this days.
This is interesting. Theres no way that all 66 models had the exact same standardized pad size (19mm) as I think OD has their propietary pad size for some of their models.
I wonder how the data would look if you isolated all the 19mm size models only. Would the interval remain the same? Or is a different pad size not enough to warrant a change in gap width dimensions?
How did the gap sized change with time? Is there a trend in the difference between gap widths with older models vs newer models?
One last thing. Which yoyos are representatives of the ends and middle of the spectrum?
