What is the lowest round of golf any group has truthfully shot or seen in a 4 person scramble on a TPC course?

I recently played in a 4 man scramble at the Four Seasons in Dallas Texas. This is the TPC course played during the Byron Nelson Tournament. Anyone who volunteered at the tournament was able to participate in the best ball scramble. The winning team consisting of 2 women and 2 men supposed shot a 51 on the par 70 course. Just seems a little fishy to me. Making a birdie on every hole except the one they eagled!! Come on that is a little far fetched. I’m just curious how low the scores usually drop during a scramble. This was the first I have ever played in. Definitely fun, but a little disappointing at the end when the scores are read out.

I DON’T THINK ANYONE HAS TURNED IN A TRUTHFUL SCRAMBLE SCORE CARD IN THE HISTORY OF THE GAME. I HAVE PLAYED IN MANY AND HAVE SEEN SCORES AS LOW AS 53, THE HONESTY OF GOLF GOES AWAY IN A SCRAMBLE, THEY JUST WANT TO WIN…
