Compression is a measure of how much force is required to deform a golf ball. The higher the compression value, the more force required. Consistency in that value matters because a ball that compresses differently from shot to shot produces different results from shot to shot. Ball Lab measures every ball individually and tracks the average and the spread across the sample.
The 2025 PXG Xtreme Tour averaged 91, putting it in the firm range of our database. Compression consistency graded out at B- with a delta of 8.5 points and a spread running from 86.8 to 95.3. That’s slightly better than the database average of 9.6, although a spread of 8.5 points still suggests some ball small ball speed variation is likely.
Ball Lab also measures compression symmetry which is distinct from the delta measurement. Where the delta tracks variation across all 36 balls, symmetry tracks how evenly compression is distributed across three points on each individual ball. The PXG Xtreme Tour averaged 1.0 points of symmetry deviation, well below the field average of 1.9. The strongest result on the card.
The charts below detail the compression measurements in our sample.
