Highest overall score attained ?

I know 180's in a specific category may happen from time to time in a category...

I'm just curious as to the closest you may be aware any team has gotten to a perfect 720 overall score at a decent sized sanctioned contest (30+ teams ??).

I looked at the score sheets at the contests we competed in this year. the overall winners scored 635, 660 and 666 (rounded up).
