I DO NOT UNDERSTAND THIS! When you take number 2, the very next person has 4, 3, and 1 to choose from. 2 of the three choices are next to you. Most people would pick either 1 or 3, and hope that you got done sooner than later so they could have their own space AND then have the buffer zones, too. Them picking 4 exposes them to the same risk YOU exposed yourself to--guy on #5 gets done, and then the next entrant has to make the same hard decision YOU just made him make.
1 or 3, but 4 is out of the question, and 2 is just asking for trouble.
