I have downloaded TESS data from the MAST site ( where most variable stars will have some TESS light curves) and plotted the superoutburst from Sept 2019. TESS stares continuously at a fixed point for about 27 days recording red light from about 20,000 targets. Stars round the ecliptic poles receive almost continuous coverage for a whole 12 months campaign so those in Draconis are well favoured.
The plot shows the first part of a superoutburst with well defined superhumps. The Y axis is in raw flux and not in magnitude.
