Looking at the chart at first is surprising,
Then reading the fine print below the chart.
Makes it look like the bad units are the last 2.
Tempstar and Goodman are the only ones over 20

It said anything less then a 5 pt difference was not meaningful. So if you compare the goodman to tempstar then it's not meaningful.
