Funny you should mention that. In a thread which has been lost to the sands of time (and the action of a moderator), Andrew all but admitted he couldn't beat the RAO. That's why I don't think you'll ever see him test it. And it's also why I keep bringing it up.
I have no reason to contact Extrema Ratio. They're not the ones that are out there putting everybody else's knife locks down but their own.
I should also mention that Cold Steel recently instigated a lawsuit over the use of the term "virtual fixed-blade" used by one of its competitors to describe the locking strength of some of their folders. But to date, I see no evidence that it has taken on Extrema Ratio over the use of the term "real fixed blade" to describe the locking strength of the RAO.
In a test between the RAO and a Tri-Ad folder, the smart money would be on the RAO.
