If by "randomised lateral offsets" you mean the Strategic Lateral Offset Procedure ( on Centre Line, or 1 or 2 miles right of your Assigned Track) on recently jaunts across the Pond I reckon there's been a pretty even spread of offset use....
"now common mid-atlantic wake turbulence experienced" (sic)..really? Can I ask why you are assuming that this turbulence you're experiencing in mid-Atlantic is of the wake variety? You've mentioned the Jetstreams: yep, we often fly in and close to the Jetstreams when Eastbound..and there is almost always significant turbulence associated with the Jetstreams themselves so a few bumps are usual on Eastbound Flights.
Whilst wake turbulence encounters do happen on the Atlantic they almost certainly don't happen on most flights.
