Ping Pong Circulate should be envisioned as two separate Circulate paths. There is an
inside path and an outside path. Sometimes, a caller
may activate only one of the Circulate paths (e.g., Ping Pong Circulate, Girls go twice; or,
Boys only Ping Pong Circulate). EN: 100
Once I heard a caller call Ping Pong Circulate 1 & 1/2.
He wanted a Ping Pong Circulate followed by an Extend.
In my opinion, this is a cute gimmick, but technically incorrect. EN: 140
Single Ping Pong Circulate[C4]:
From a Single 1/4 Tag.
As one movement, Extend twice and the new Ends U-Turn Back.
Ends in a Single 1/4 Tag.
The direction toward which to do the U-Turn Back is undefined, hence it is inappropriate
to follow this movement with a Roll. EN: 583
