It does not make a large difference in practice: situations are rare at the evaluated facilities where the  current drops from the nominal beam current to less than 50\% but not to zero.   ``low-beam-current'' ``Low-beam-current''  events will vary significantly with the definitions of the $I_{\hbox{tol}}$ current limit. At Spring-8, for example, a beam decay of about 0.1\% starts a ``low-beam-current'' event,   while at BESSY-II it starts only at 9\% beam decay.   The reason of this difference comes from the required current stability for the experiments  that can differ significantly between light sources.  The number and duration of "Low-beam-current" ``low-beam-current''  events do tell how well a facility meets their promised beam current stability.  Table~\ref{tab:pf-limits} shows the current limits for the primary
