By fixing a set of starting assumptions, we can compare other information over a large data set. For Victor recordings, the specification is to tune them all to A=440. By looking at the distribution of speed adjustments, we can learn whether there might have been a different common reference (A=435?) in some region or period. For Edisons, the specification is RPM=80. How does the reference pitch then vary? Similarly, do any patterns emerge when viewing stylus selection? Working with unusually high quality source discs, our stylus size selections need not compensate for wear and poor condition.
