So it says. But, the 'space method' could be interpreted as being under the "Simple Overlap" fallback rendering method, since the paragraph from which you are quoting appears immediately after the paragraph treating with "Simple Overlap" method. In the first paragraph under "Fallback Rendering" (bottom of page 120), the "Show Hidden" method is described. It would have been redundant to say that degenerate cases **under the "Show Hidden" method** need to be displayed as if on a dotted circle, since the "Show Hidden" method is **all about displaying on dotted circles** whenever there is an inability to draw the sequence. Like, in the event of an invalid sequence. Whether to use "Show Hidden" or "Simple Overlap" method to display invalid or degenerate sequences should be left up to the various software developers. It does seem to be very easy to spot bad input when the dotted circle appears in the display. Stands out like a sore thumb, which was probably the intention. Perhaps this section of T.U.S. could stand some clarification. Best regards, James Kass .
