Doing 3 packer briskets and need input

Unknown

I am doing brisket for 60 this weekend and will be doing three packer briskets of around 13 lbs. each on the XL BGE.

I have done one brisket of such size many times with great success in the past. My main worry is about the time of cook. It usually takes around eight hours in the 230-240 range for one brisket to get to 190 or so.
Should I add significant time when doing three briskets? I have to walk out the door for the party at 5:30 so I won't have any margin for error.

Thanks for any and all feedback!.

Here is a link I did afor 2 packers 2 weeks ago. Granted they were frozen for a week and reheated, but worked out great. As Pat the originator said not the normal way, but great.
