  In a recent article, we proposed an energy correlator-based method to achieve
a precision top quark mass extraction from jet substructure, using the
$W$-boson mass as a standard candle. In this paper, we perform an extensive
event generator simulation study of this proposal, testing both its
experimental viability, as well as its sensitivity to different subprocesses in
the top quark production and decay. On the experimental side, we show that
uncertainties in the jet energy scale, constituent energy scale, and tracking
efficiency have a minimal effect. On the theoretical side, we find that our
observable isolates the perturbative decay of the top quark, while
nonperturbative physics, such as the modelling of color reconnection, and
underlying event, have a negligible impact on the distribution. We conclude
that our proposed measurement is resilient to the experimental and theoretical
aspects of the hadron collider environment, with variations in model parameters
consistently leading to $\lesssim 100~$MeV shifts in the measured top mass. Our
results motivate precision theoretical calculations of the energy correlator on
top decays, both analytic and using parton shower generators, and further
exploration of the experimental measurement.
