For several facilities this is currently not the case. ALBA, BESSY-II and LSLS-UVX consider a  closure of the photon shutters by an interlock equivalent to a loss of the electron beam.  For some facilities a ``no-beam'' failure stops not when the beam is back to   the nominal current $I_{\hbox{nom}}$ but when the interlock is cleared that prevents the beamline shutters from opening (ALBA, BESSY II, LNLS-UVX) LNLS-UVX, SPring-8)  or when the insertion devices move back to their closed positions (SLS).   PETRA III adds an amount of time to allow for the warm-up of the optical components at the beamlines.   These practices are oriented to use a beam availability understood as photon beam availability.

Nevertheless comparing the tolerated beam decay is still useful   to judge the promised current stability of a facility.  For those facilities where the limits are similar, the failure rates will allow a  meaningful comparison of the reliability of the injection process.
