So, does the vertical axis of this graph this graph indicate shock stroke movement? If so, then this would mean the suspension is stiff in the "sag zone", more soft/supple through the travel, and with a good ramp-up in stiffness at the end of the stroke.
Y Axis is the compression ratio (shock vs travel) while x axis is wheel travel. Because the compression ratio is higher in the beginning, it's more supple.
Have I understood correctly?
