Conjecture on extreme values of derivatives of the zeta function

Let N\ell\in\mathbb N be fixed, and let Y\mathbf{Y}_{\ell} denote the constant used in the source.

Derivative extreme-value conjecture. As TT\to\infty,

maxTt2Tζ()(1+it)Y(log2T)+1.\max_{T\leqslant t\leqslant2T}|\zeta^{(\ell)}(1+it)|\sim\mathbf{Y}_{\ell}(\log_2T)^{\ell+1}.

This conjecture extends the expected extreme-value scale for ζ(1+it)\zeta(1+it) to its derivatives. The supplied text does not establish the asymptotic or indicate a resolution.
