The superoutbursts of normal SU UMa stars, such as VW Hyi, have been shown 
to be triggered by a normal outburst as well. These normal SU UMa stars
have also regular normal outbursts in between their superoutbursts.
In that respect it might be different to the so-called TOADs or 
WZ Sge stars, which have not yet shown to be triggered by a normal outburst,
and show (almost) no normal outburst in between superoutbursts
(with very long recurrence times), except just after the outburst,
such as indeed EG CnC and UZ Boo.
