Abstract
In this work I discuss briefly the calculation of the algebraic entropy for
systems of quad equations. In particular, I observe that since systems of
multilinear equations can have algebraic solution, in some cases one might need
to restrict the direction of evolution only to the pair of vertices yielding a
birational evolution. Some examples from the exiting literature are presented
and discussed within this framework.
