Where this data comes from

RDQ publishes the Badass 2 bench table as the listing's own description image (1507_-_info_4.1.jpg): Item NO. / Prop / Throttle / Volts / Amps / Watts / Speed (RPM) / Thrust / Efficiency, six throttle points per run, temperature measured on the motor surface after 15 s at 100% in a 26 C room. Each winding's spec-block Peak Current / Max Power / Max Pull is its own GF4023 100% row (19.7 A / 437.3 W / 868 g at 22.2 V on 2650 KV; 28.2 A / 417.4 W / 798 g at 14.8 V on 4000 KV). Internal resistance is 160 mOhm at 2650 KV and 84 mOhm at 4000 KV. One row is not published: the 4000 KV GF3056 50% point prints 1899 g and 37.74 g/W, where the same winding's other two props read 239 and 328 g at 50%.
