I agree with you, that is why I said it is not Scientific. I have also watched a couple of other videos and it seems as if the Coleman and the Cabelas are the two best for holding ice with the Ozark and the Yeti Models behind them.Neat video but even he mentions that the 72 and coleman loose ice faster because of the volume. If you had them all filled based on their volume rather than just the same quantity of ice, they would both probably perform better than they did in his video. That's just my theory though.
