I think that's our points as well. You seem to be the only one that has heard of this. You have no correspondance to verify this. We're all in regular contact with Bell. We still have 97% cruise in our manuals.
What if I told you that Bell said you can't start engine #2 first (they didn't say this). Would you then change your procedures? Even if nobody provides evidence or even supports this claim?
It's not that we don't trust you, just that a change like this requires more than one opinion from the internet.
