In the case of VW Hyi, the maximum gap between the peak of the normal outburst and the detection of the subsequent superoutburst is ~5 days, whereas the maximum of the 2007 outburst of NN Cam occurred some 9 days before the detection of the superoutburst.
This has, for example, been demonstrated in the case of VW Hyi over a multiplicity of superoutbursts (18) and recently the remarkable similarity of the lightcurves of the 2001 and 2009 superoutbursts of CP Dra has been shown.
