Starting formation - 2 x 4 formation.
Do a total of four SPLIT CIRCULATES, except that when you become an In-facing Center do your next
CIRCULATE to your diagonal opposite position (crossing over into the other Box). Exchange The Box
can be fractionalized into fourths. The traffic pattern is such that as you are crossing to the other Box,
you must physically stay to the outside of those who are still in their original Box. The In-facing Centers
lead the Exchange and usually everyone else in their Box can follow them.
