Thanks for your clarifications...
Hm.... Perhaps I've missed this.... are the variables/parameters determining the values of the Stall Warning Threshold function and thus the shape of the curve valid, for the entire time (X) axle in the graph?
If NOT, then, "invalid", or "non-defined values" for the variables determining the values of the function/curve, means "invalid" or "non-defined function values", which means segments of curve which would be "invalid", or "non-defined". This means that the "non-defined" portions of the curve can be represented accurately only as a discontinuity - gap - on the non-contiguous curve.
Ultimately, it does not matter much, as these curves are just an illustration to help the understanding and communications of info on this thread.
