The combo was clearly not average.
It was the highest scored element in this competition. Much better than average. Epic? maybe not.
The combo is average. It has high base value, but it's not a spectacular combo. The judges gave her appropriate GOE for that. You can't compare BV of one combo vs. another. Just like you can't compare an average 4T-3T combo with a spectacular 3F-3T.
Hence, adequate 4T-3T vs. great 3F-3T. There's a distinction.
