	\begin{columns}
		\column{0.8\textwidth}
	\begin{itemize}
		\item Carbon fiber+Kapton backing for half-modules is not perfect (same shape and size as sensor with no cutouts, L4-6 might be missing CF): thinner than silicon, shouldn't matter
		\item Hybrids are missing in L4-6: not a big deal
		\item SVT structure mostly missing (base plates of U-channels and SVT box are in), Al cold blocks missing: matters at the edges of acceptance
	\end{itemize}

	\begin{itemize}
		\item For the trident problem: no
			\begin{itemize}
				\item Data-MC disagreement is everywhere in phase space

		\item At the edges, maybe
			\begin{itemize}
				\item Can change trigger or matching efficiency
