\section{PROPOSED SCHEDULE STATISTICS}   Some facilities are very flexible to compensate users for long beam outages.   Either some of the machine development shifts are sacrificed just after a long beam outage, or pre-scheduled blocks of shifts are used to re-schedule users, when problems with the accelerator prevented them to finish their experiments.  The accounting of these These  compensation times is are  currently facility dependent. accounted for in very different ways, depending on the facility.  We therefore propose a unified metrics for the accounting of these compensation the user operation  times. User operation should be distinguished in three categories:  \begin{itemize}  \item {\em Scheduled User Experiment Time:} time allocated for user experiments at least one month in advance.  \item {\em Scheduled User Reserve Time:} time that was scheduled at least one month in advance, but  not allocated for experiments. This time is reserved to re-schedule users that could not finish their measurements.  \item {\em Spontaneous User Time:} time that was originally not scheduled for user time, but was re-assigned to the users less than one month before, for example as compensation for recent accelerator problems.  \end{itemize}

According to our proposal this will be accounted for as a seven day or 168 hours ``No-beam'' event.  The extra seven days are {\em Spontaneous User Time}. The total user time will be 4168 hours.  If the shortened shutdown would be more than one month into the future, then the extra seven days would be accounted for  as {\em Scheduled User Reserve Time} instead, otherwise there would be no difference.
