Cooking three tri tip on the Weber tomorrow. I set it up coals on one side tips on the other. I've got it fairly dialed doing one. Taking right at about 40-45 minutes on the grill and then about a 15 minute rest in foil for one. Im assuming once i pull them rest time will be the same. My question is how much longer will it take to bring to temp doing three? I've not cooked in bigger batches a lot but have run into situations with chicken when cooking a lot of quarters vs two or three that it takes a fair amount longer. Trying to land these coming off the grill and being done at the correct time. Thanks for any input.
