## Part I - Introduction, Definitions and Shorthand Notation

(D) The Shorthand Notation

The line description of a Step Model is read left to right, using the following standard notations. All distances are in inches and all angles in degrees.

R = right
L = left
S = step-line
C = carry-line
A = aberration
St = stride-line
FO = (2) = foot offset given as 2 degree leg angle
FA = 5L = 5 deg foot angle left
PO = <5>L = 5 deg push-off angle left
SO = 15 = step-out-line = 15"
PS = {-2} = pelvic-stretch = -2", (negative value means rear-stretch-line is decreased, a CCW rear-pelvic joint rotation)
RL =  = rear-leg-line = 15"

L15{2}str8: (2)L-2L-<4>R ( A straight left step.) = left foot step-out-line = 15”, pelvic-stretch = 2", rear-leg-line = 15", straddle-line = 8": (2deg leg angle) offset left (CCW), 2 deg foot angle left (CCW)and 4 deg push-off angle right (CW).

LA:2.5(36.5R)-16R = left foot aberration : 2.5 cm heel-point shift at 36.5 deg right (CW) from foot-line - 16 deg right (CW) foot-line rotation.
