So when a plane goes down you blame the pilot not the aircraft
Not sure if that comment was meant as criticism, or statement of fact....but in this case, yes. Pilot error.
The point of the QR is to do exactly that - release quickly, especially under tension, with minimal input required, when in an emergency situation (eg deathloops).
In this case, Ruben's technique is to fishpole his bar, and at the same time pull the bar fully in to choke down on the QR, to megaloop. He does this by positioning his left "pull" hand in the middle of the bar, jamming it up against the QR. As the kite powers up and pulls the bar, his hand catches on the QR and provides the minimal input required to release it. The difference being he is mid-megaloop 15m in the air, rather than being dragged along the ground/water by a deathloop, so the release is unwanted. If anything, it demonstrates that Ozone's QR works perfectly, even under the extreme forces produced by a deathloop/megaloop.
Unfortunately, this incident is down to his hand-positioning when looping. If he were to have his left hand out from the middle of the bar, so that it is positioned below the QR when he fishpoles, then there'd be no issue. Be interesting to see what his technique is when looping the other way (ie right hand is pull hand).
The priority for a QR, as an emergency device, has to be it's ease of release under tension. We shouldn't be trying to modify them to make them harder to release IMO. This wasn't a case of a faulty release (ie releasing without being triggered), this was a case of accidentally triggering the QR to do exactly what it was designed to do. The solution is for Ruben to modify his technique.
