How I measured this
Every number in this review is one I measured with my own equipment and instruments. Swing weight on a Briffidi SW1, twist weight on a Briffidi TWA2, static weight on a precision balance scale, serve speed and punch volley speed with a radar gun, spin from a high-speed camera at over 500 frames per second, surface roughness with a stylus roughness tester. It's the same setup for all 638 paddles I've measured.
R1 Ripple 14mm: Swing weight 111.44 · Twist weight 5.62 · Spin 2,392 RPM · Static weight 7.67 oz · Serve speed 62.5 MPH · Punch volley speed 39.3 MPH
R2 Ripple 14mm: Swing weight 104.65 · Twist weight 6.26 · Spin 2,380 RPM · Static weight 7.64 oz · Serve speed 62.8 MPH · Punch volley speed 39.2 MPH
If a metric is missing above, that paddle hasn't been through that test yet. Full measurements for each paddle are on its paddle page. My method is written up on the methodology page, and every paddle I've measured is in the paddle data study.
