Unfortunately no.. Most of the testing using this method are only done inside wind tunnels. Their main priority are vortices (for fuel efficiency)
and very minimal to the wake that the aircraft produces. Most wake distance guidelines are calculated estimates since wind conditions can come from different directions.
Well in this case, since most pilots are experiencing wake turbulence even at the set distance from the double decker. I do hope somebody (or an authority would make an inquiry about this and hope that no accidents happen before they can set up some new guidelines.
