Trying to find a fire fight leader board

Hi Guys,

I’m looking for a list of the highest co-op (4 player online match making) fire fight scores. I can’t find it anywhere. I checked Halo Charts, Halo Tracker and

On the left side of the screen on you can see your leaded boards for this score compared to your friends, but I’m looking for world wide list. Any one know where I can find this? Any one know what the highest score is?

no idea, but that would be fun if it could be kept clean.
