I can tell you that the #5 guild didn't get it. By the time we got 35 wins, there was only @ 19 hours left in the war. And we only had 65 battles in the 71 hours.
I've been told that RP didn't get it.
Warlord said it was impossible.
Haven't heard back from RK yet, but I think it was impossible to get 67 wins in during a 71 hour war.
