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.
