It kept going like that... but … THOSE MUDDY FOOTPRINTS! All this didn't shed the mud! Approved terminology was an anchor. A huge question was “What is midstance?” By time? By progression distance? But what was STANCE and what was SWING (again muddy footprints). How do we relate the x,y,z graphs to the actual thing seen? [ maybe stop here & read the MUD book first]

Y axis is whatever thing is being plotted vs X = time. Mark the time axis with “events” [things seen]. Right heel strike (RHS) etc.. Things seen in the MUD? Mostly. But a grimace could be an event.
