This works for me. Have four of the six people in your party that you plan to df with. Wait for a number that sums up to 5, and is less then 4 minutes, but more then 2 minutes. That number must be even too, so something like 2:12 is good. Then when there is 30-45 seconds left, add the 5th member. Next when its 30-20 seconds left, add the last member. Then I usually stand up and go outside for a minute. If its raining, go drink water, if its sunny, have cool aid. If its an overcast, run around the house once. Then call your dog. If you dont have a dog then you wont always get in to df.
