These are estimates, not measurements
We calculate these scores from the manufacturer's published specifications using a formula we publish in full. Nobody has swung this paddle on our behalf and nobody has put it on a swing weight machine. Treat them as a way to compare paddles consistently — not as lab data.

Where these numbers come from
This site is an aggregate database. We test nothing and measure nothing ourselves. Every number above is a named source's published work, credited and linked back to the page it came from. Where 2 of them measured the same thing, we average it and show you every individual reading. The aggregated score is the combined judgment of the reviewers named above, never our opinion of the paddle. Reviewers' numbers never feed the derived estimates further up the page — those stay our own calculation from published specs. How we combine sources
