  Castellano, Ruiz, and Valenzuela recently observed a remarkable "pattern" in
infinite-distance limits of moduli spaces in quantum gravity, which relates the
field space variation of the mass of the lightest tower of particles to the
field space variation of the species scale. In this work, we show how a version
of this pattern can be proven to hold for BPS particles and strings throughout
the vector multiplet moduli space of a 5d supergravity theory, even in regions
where the particle masses and string tensions are substantially modified
relative to their asymptotic behavior in the infinite-distance limits. This
suggests that a suitably defined version of the pattern may hold not merely in
the asymptotic limits of moduli space, but in the interior as well.
