MUD Mired in time...

Ooo, if only this mud had come from a magnetic magic gush where the crystals form as they cool to tell us that it was 1.2 seconds from A to C [a right heel strike to the next right heel strike]. Period=1.2s If the distance from A to C indicates a relaxed walk, then we know the height of this walker. One full walking cycle length is 75% of the walker's height ( stature ). This assumes a relaxed walk in a person who is not wounded nor carrying a load. From one gait foot-print detail to the next occurring same side same detail is called a STRIDE. Teaching stuff nearly always uses a right heel strike to the next right heel strike as defining one STRIDE. We can see that 1 stride contains 2 STEPS - A to B then B to C. A left step and a right step = one cycle. So, although we chose to begin with a right heel strike (at A), our first mud documented step is the LEFT step, the one swinging and then landing (A to B). Yes, everybody measures this distance and then they call it the “left step length”. You see this everywhere. They will give you the left step length and the right step length. They will list every % thing that can be made of any two mobile things. (Following this? Sorry. It is all wrong, but we'll let you suffer a bit.) Now, we jump ages ahead. Instead of mud we go to the computer lab seeking GIGO. The big improvement is the absence of gnats & mosquitoes though bugs persist. The terminology now being used is still stuck in that mud along with those muddy implications. This means that the thinking of possibilities is also mired. The lab also tells you the knee had one angle over here and then had another angle over there with a continuous graph of knee angles through the whole cycle.
