Skating technique features common to all athletes.

Technique	FwdA	SideA	UpA	Roll	Pitch	Yaw
G2	1 double peak each cycle (for some athletes a minor+major peak)	regular cycle identifies skate left vs. right	asymmetric peak preceding FwdA peaks	clear Roll peak >50 d/s follows Yaw peak	peak >50 d/s identifies poling	clear Yaw peak/trough cycle following SideA
G3	2 even peaks each cycle (left/right)	regular cycle identifies skate left vs. right	one main peak, between FwdA peaks	irregular peaks <50 d/s	peak >75 d/s identifies poling; 2 Pitch peaks for every Yaw peak	clear Yaw peak/trough cycle following SideA
G4	1 minor peak each cycle (skate) 1 major peak each cycle (skate+poling)	regular cycle identifies skate left vs. right	one main peak, coinciding with minor FwdA peak	asymmetrical peaks generally < 50 d/s	peak >75 d/s identifies poling; 1 Pitch peak for every Yaw peak	clear Yaw peak/trough cycle following SideA
G5	2 even peaks each cycle (left/right)	regular cycle identifies skate left vs. right	minimal but rhythmic	clear Roll peak >50 d/s follows Yaw peak	peaks <40 d/s much less than G2-G4 (no poling)	clear Yaw peak/trough cycle following SideA
