  Inspired by [Qiu, Wilson 2019] and [D'Adderio, Iraci, Vanden Wyngaerd 2019 -
Delta Square], we formulate a generalised Delta square conjecture (valley
version). Furthermore, we use similar techniques as in [Haglund, Sergel 2019]
to obtain a schedule formula for the combinatorics of our conjecture. We then
use this formula to prove that the (generalised) valley version of the Delta
conjecture implies our (generalised) valley version of the Delta square
conjecture. This implication broadens the argument in [Sergel 2016], relying on
the formulation of the touching version in terms of the $\Theta_f$ operators
introduced in [D'Adderio, Iraci, Vanden Wyngaerd 2019 - Theta Operators].
