Key Metrics and Definitions:

LOW and HIGH: These figures show the actual measured range across the dozen balls tested.
MEDIAN: This is the single figure sitting in the middle of that range, which is the easiest number for your audience to use for direct model comparisons.
The Scale (35 to 104): This represents the compression scale itself. A lower number indicates a softer ball, while a higher number indicates a firmer ball.
The Colored Bar: This visually displays where a model landed, with the highlighted section marking its specific compression range within the measured dozen.

What Compression Means for Golfers:

Compression is essentially a firmness rating that describes how much a ball gives upon impact. Softer, lower-number balls compress more, which often results in a softer feel and more movement off the clubface during chips and putts.
