I think this thread has slipped in to the twilight zone
Anyway, don't worry too much about the adjudication date that you see on Visa Journey - it's just an estimate based on everyone entering their timeline.
It is not official and it is not connected to the USCIS.
Sometimes people take a long time to be approved, sometimes a short time - sometimes people enter incorrect dates in to their timelines by mistake.
Hang in there!
