It is a well-known result by Saks \cite{Saks1934} that there exists a function so that for almost every $(x,y)\in ^2$ where . In this note we address the following question: assume we have two different collections of rectangles; under which conditions there exists a function $f \in L^1(^2)$ so that its integral averages are divergence with respect to one collection and convergence with respect to another? More specifically, let and consider rectangles with side lengths in and respectively in . We show that if the sets and are sufficient ``far" from each other, then such a function can be constructed. We also show that in the class of positive functions our condition is also necessary for such a function to exist.
