We show that if an Ahlfors–David regular set E$E$ of dimension k$k$ has Big Pieces of Big Pieces of Lipschitz Graphs (denoted usually by BP(BP(LG))$\mathop \mathrm{BP}(\mathop \mathrm{BP}(\mathop \mathrm{LG}))$), then E⊂E∼$E\subset \tilde{E}$ where E∼$\tilde{E}$ is Ahlfors–David regular of dimension k$k$ and has Big Pieces of Lipschitz Graphs (denoted usually by BP(LG))$\mathop \mathrm{BP}(\mathop \mathrm{LG}))$. Our results are quantitative and, in fact, are proven in the setting of a metric space for any family of Ahlfors–David regular sets F${\mathcal {F}}$ replacing LG$\mathop \mathrm{LG}$. A simple corollary is the stability of the BP operator after two iterations. This was previously only known in the Euclidean setting for the case F=LG${\mathcal {F}}= \mathop \mathrm{LG}$ with substantially more complicated proofs.
