abstract = {Extrapolations of sensitivity to new interactions and
standard model parameters critically inform the programme at
the Large Hadron Collider (LHC) and potential future
collider cases. To this end, statistical considerations
based on inclusive quantities and established analysis
strategies typically give rise to a sensitivity scaling with
the square root of the luminosity, $\sqrt{L}$. This suggests
only a mild sensitivity improvement for LHC's
high-luminosity phase, compared to the collected data up to
the year 2025. We discuss representative analyses in top
quark, Higgs boson and electroweak gauge boson phenomenology
and provide clear evidence that the assumption that the
sensitivity in searches and measurement scales only with
$\sqrt{L}$ at the High-Luminosity LHC is overly conservative
at best, and unrealistic in practice. As kinematic coverage
enables more targeted search strategies with sufficient
statistical sensitivity, employing a multitude of features
in data dispels the scaling based on more inclusive
selections.},
