  Using the Fredholm setup of [12], we study genus zero (and higher) relative
Gromov-Witten invariants with maximum tangency of symplectic log Calabi-Yau
fourfolds. In particular, we give a short proof of [23, Conjecture 6.2] that
expresses these invariants in terms of certain integral invariants by
considering generic almost complex structures to obtain a geometric count. We
also revisit the localization calculation of the multiple-cover contributions
in [23, Proposition 6.1] and recalculate a few terms differently to provide
more details and illustrate the computation of deformation/obstruction spaces
for maps that have components in a destabilizing (or rubber) component of the
target. Finally, we study a higher genus version of these invariants and
explain a decomposition of genus one invariants into different contributions.
