How can I call Split Phantom Lines In Roll Circulate?
In all concepts that can specify either lines or waves, the “waves” version has an implicit assume waves operation in it. Under normal circumstances, this means that the live people can make use of the assumption of waves in order to decide how to start the call. For example, in normal columns, split phantom waves in roll circulate, which is equivalent to split phantom lines, assume waves, in roll circulate, is legal, since the phantom in-roller’s location can be deduced from the wave assumption. The call split phantom lines in roll circulate is illegal from columns because the facing direction of the phantom in-roller is unknown.
