Split time Opposite direction
The hands circle in opposite directions. One reaches the bottom halfway between the other's downbeats.
In this upright view, one reaches the top as the other reaches the bottom. Their paths mirror each other across a horizontal line.
Try timing and directionIn practice
A split-time poi butterfly uses this relationship. Its downbeats alternate.
Timing and direction
Split time also exists in same-direction motion. Add the direction to distinguish a split-time butterfly from a regular weave.
