Summable Hausdorff measure conjecture for singular strata of Alexandrov spaces

Let n\mathdsNn\in\mathds{N}, let kk be a nonnegative integer, let (X,p)Alexn(1)(X,p)\in\operatorname{Alex}^n(-1), and set

ϵi=2i.\epsilon_i=2^{-i}.

Here Sϵik\mathcal{S}^k_{\epsilon_i} denotes the ϵi\epsilon_i-singular stratum and Hk\mathcal{H}^k is the kk-dimensional Hausdorff measure. Summable Hausdorff measure conjecture. One has

i=0ϵi+1(nk)1Hk((Sϵi+1kSϵik)B1(p))<C(n).\sum_{i=0}^\infty \epsilon_{i+1}^{(n-k)-1}\mathcal{H}^{k}\Big(\big(\mathcal{S}^{k}_{\epsilon_{i+1}}\setminus\mathcal{S}^{k}_{\epsilon_i}\big)\cap B_1(p)\Big)<C(n).

This is presented as a stronger summable form of the preceding quantitative Hausdorff measure conjecture, with the source pointing to an example as motivation. Its status is not resolved in the provided source context.
