lol, it was 5...
No one is seriously going to count Sha Gi, who was shit even by padawan standards, and lost his nerve and got crushed before the fight even began. 3 of the 5 were nothing to write home about, and all 5 were exhausted from hours of fighting.
Big difference between 12 and 6, big difference between 6 and 5 exhausted Jedi, 3 of which are garbage anyway.
