The higher special-point obstruction conjecture

Let i>1i>1, let viv_i be the relevant rational accumulation point, and let bib_i be the corresponding parameter. Let cHbic_{H_{b_i}} be the capacity function, and let (3,1;2,1×5)(3,1;2,1^{\times5}) be the nonperfect exceptional class whose obstruction is equivalent to the obstruction from the 8th ECH capacity.

Higher special-point obstruction conjecture. For i>1i>1, cHbc_{H_b} has no descending staircase. Furthermore, there exists ε>0\varepsilon>0 such that, for

z[vi,vi+ε),z\in[v_i,v_i+\varepsilon),

the capacity function cHbi(z)c_{H_{b_i}}(z) equals the obstruction from the 8th ECH capacity, equivalently from the nonperfect exceptional class (3,1;2,1×5)(3,1;2,1^{\times5}).

The claim extends the established description at b=1/5b=1/5 to all higher indexed special points. The supplied text describes it as experimental evidence rather than a proved result.
