Bryan, I saw all that, but I think all that applies to Table 4 and 5, but not Table 6. For example, "the hammer protocol" was with a hammer at 143.8 fps. For Table 6, they used a golf club head at 160 fps (the USGA test number.) Before Table 6:
In addition to the above indicated test results, the distance and playability properties of the more preferred formulations of the present invention (i.e. Examples 19 and 22, which are representative of the chemical composition of Spalding's new, longer distance and slightly softer, Tour Edition combinations of Spalding's current Tour Edition Edition as a number of competitive golf balls, and the following performance results were produced.
I don't think they specified ball speed, and I don't think the ball speeds are all the same. I think those are just the numbers for the calibration ball. I think they only specified swing speed, and only reported distance results. Likewise I don't think they picked that spin rate.
Picture this. They go out to their iron byron. Set it to 160 fps. Tee up a a calibration ball. Hit it. Record the resulting ball speed (239) and the resulting spin (3232) for calibration purposes (maybe to make sure machine is still working the same as last time.) Then do the experiment, only recording distance.
It is a hard read, but that is the best I can figure it.
