Re:New bike chain claims to be faster, more durable

Just had an idea [1] about how this "gripper chain" could maybe outdo a roller chain in efficiency:
Maybe the "gripper plates" align themselves perfectly with the tooth at a time when the connection is still not under load yet? A conventional roller won't need much aligning, but it won't do that, it won't settle into place before load is applied. Friction scales with force. If that's how they teased out a minor delta then it's truly very clever (but likely still highly impractical outside the laboratory/indoor track setting)
[1] idea came while taking a shower, were else. Shower after churning that old Campag 12s chain a little, unfortunately only on Zwift these days
