I think Harvard Lone Gunmen vs. Penn A at
Sectionals may have topped 830, and might also
(unfortunately) count as the worst bludgeoning in NAQT history.
Although I don't remember the exact statistics, I do
remember that Harvard won by over 600, and that Penn did
have at least 115, so therefore, 2 x 115 + 600 = 830
at least.
