   Although everything may be literally possible, is there any reasoning
to "believe" that very fast outbursts or precursor outbursts are equally
likely?  The stunted outbursts Kent Honeycutt referred to were
small-amplitude outbursts in novalike or post-nova systems, which are
unlike from dwarf novae in that they mostly have thermally stable accretion
disks.  The fraction of dwarf novae among RoboScope targets is much smaller
than Arne's description would suggest; their main targets have been
(poorly studied) novalike systems and occasionally dwarf novae.
