11 is too low to make sense from a statistical perspective. But I agree in part with you, I am not sure of how likely is that an out of air buddy will grab the regulator I am breathing from... I dive the long hose for several other reasons (and just to avoid other flames, it's my choice, I do not judge people who dive standard octo, which is a fine choice as well).
I fully agree with you.
My point was not that anyone should dive a long hose to counter the possibility that a OOG diver will snatch your primary second stage (there are more valid reasons).
@Happyladydiver mentioned that she has a self-service approach because she expects an OOG diver to be stressed enough to just grab it and not wait for his/her buddy to donate.
As such, if you believe this is the case, better to plan for the possibility of this out-of-control and gas diver to grab your primary.
