The four walls at nine levels, 40 starting angles on the published rises

One row per level from a fifth to four fifths, with a mark at the rise where each exponent's settling share crosses it and that row's ordering of the four printed beside it. Five of the nine levels resolve at this sampling and they give four different orderings of the same four exponents, read off the same runs. The ordering at a half is 5,2,4,3, and it is one no other level gives. That level is the shaded row. A level the curve never reaches has no crossing to interpolate and is refused rather than reported with a hole in it.
