 The re-ordering arguments involving dominant and subordinate stamps (i.e. $\domStamp$ and $\subStamp$) rely on some constants which we define here:

+Two criteria have to be considered in setting these constants.
+Let us define \col{max} as the maximum ``$\domStamp$''-offset encountered in constraints
+that is
+$\col{max} = \max \big\{ \, \col{d} \, \big \}$
+where the maximum is taken over all \col{d} which appear in a constraint of the form $\domStamp \equiv \hubLambda \cdot \col{h} + \col{d}$.
+The constants above have to satisfy
 \begin{enumerate}
-	\item for any ``dom''-offset \col{d} used in a constraint to set $\domStamp \equiv \hubLambda \cdot \col{h} + \col{d}$ (where $\col{h} \equiv \hubStamp$) it should hold that $0 \leq \col{d} < \revertEpsilon$

+	\item $0 \leq \col{max} < \revertEpsilon$
+	\item $0 \leq \finalizationEpsilon < \selfdestructEpsilon < \hubLambda$
 \end{enumerate}
+The constants proposed above satisfy the stronger condition
+\[
+	0 \leq \col{max} < \revertEpsilon < \finalizationEpsilon < \selfdestructEpsilon < \hubLambda
+\]
 Indeed reverting should happen before gas refunds and before enacting any \inst{SELFDESTRUCT}'s and ``\texttt{doing}''-actions ``taken in the moment'' should not interfere with ``\texttt{undoing}''-actions scheduled for post roll back.

 The above enforces that $\hubStamp$ remains constant throughout the processing of any transaction which requires no \textsc{evm}-execution as well as during the initialization and finalization phases of transactions that require \evm{} execution. The \hubStamp{} furthermore will jump by one (on any one of those phases) whenever the current row peeks into the transaction.
 We remind the reader that for these three phases (\txSkip, \txInit{} and \txFinl{}) the $\peekTransaction{}$ flag already played a special role in the previous section, see constraints
