LOL!!Well, I watched the video again and noticed you didn't test the sand to see how fine it was for the appropriate tire pressure.
Did you even bother to check humidity levels? the atmospheric pressure? it can greatly affect the final pressure needed for proper self-recovery.
Also noticed you didn't spin the tires fast enough to create a cool factor rooster tail when you drove away so I would say you did not recover under your own power but likely edited out the winch cable used from the other Jeep.
Good thing I watched it again, I missed so much "misinformation" in the 1st viewing.
I may not ne a professional off roader but I did stay in a Holiday Inn last night.
