There is simply no way 65 ounces of water will pass through the Chemex with enough ground coffee in 4 minutes. You would need a super coarse grind, like pebbles to make it through.
The more grinds you have and the mire water you pass through the more likely the draw down will be markedly slowed. The Chemex easily gets choked off. At high volumes. It should take about 7-11 minutes for a full 13 cup batch.

I KNOW you don't want to hear this, but there is no way the coffee will be hot enough for anyone to add 1/2 or milk without having to reheat their mug. Personally, I'd consider a large stainless vac pot like a Nicro (vintage) or Adcraft. Mine brews 50 oz piping hot. Or brew an 8 cup 40oz Chemex, decant into a Nissan, etc) thermal keeper, then do another smaller 4-5 cup Chemex.
