The Leaders footwork implies a hip rise as there is no specific mention of which rise. There are options:
Leader does Leg rise If that leg rise is greater than (Followers Heel Height - Leaders Heel Height) then the Followers heel will come off the floor
Leader does Leg rise and foot rise If that leg rise + foot rise is greater than (Followers Heel Height - Leaders Heel Height) then the Followers heel will come off the floor
Since the level of leg rise in 1 and 2 are really difficult (see least action) we are left with
Leader can perform as much foot rise as they wish but it's usually (Followers Heel Height - Leaders Heel Height) for aesthetic and least action reasons.
Definitions (for clarity):
Term | Description |
---|---|
Foot Rise | Lifting the heel off the floor |
Leg Rise | Straightening the knees |
Hip Rise | Vertical shift of the torso/COG due to either of the above |
The books often refer to 'rise' as one unified thing, but in practice, it's a composite rise vector.
