That method matters. This is not two separate sessions and not an attempt to recreate the same swing. Both programs get the same launch data, which is the cleanest way a garage tester can compare carry, total distance, flight, landing, bounce, rollout, chips, pitches, putts and the side-by-side look of the graphics. The uploader says the biggest question is the relationship between carry and total distance on matching inputs.
What the video does and does not claim
Hosel Rocket is clear that both titles are running beta software. Results are a snapshot of current development builds, not a final physics grade. The description walks club by club from driver through putter and asks which engine looks more realistic. It does not publish a single winner line in the public description, and YouTube rate-limited the transcript pull from this IP, so any specific yardage gaps belong to the embedded video rather than to numbers inventing themselves here.
