     - Conversely, if $\texttt{SignedGasPrice} > \texttt{EEGP}$, there's room for further adjustment of the gas price that will be charged to the user.
 
-3. In the previous case, it was necessary to compute a more precise effective gas price based on the accurate amount of gas, denoted as $\texttt{GasUsedNew}$, obtained during the transaction’s execution using the correct state root at the time of sequencing transactions (which was not known earlier for straightforward reasons).

     Henceforth, the Executor executes the transaction using $\texttt{EEGP}$, obtaining $\texttt{GasUsedNew}$, which the sequencer utilizes to compute a new effective gas price, referred to as $\texttt{NEGP}$.
