Backside 50/50: a terminology note
Match the term to a particular leg configuration and body orientation. It should not be used as a blanket name for every variation of the Imanari roll.
Why this page is a note
The earlier site tied a variant of the entry to this position without matching every described movement to the footage. The guide now separates the entry from its possible outcomes.
This does not establish that the old classification was false. It means that the correspondence was not established well enough to present as a fixed sequence.
