It is known that SU UMa stars change their supercycles (time length between
superoutbursts) after a certain time (several supercycles or more), see
Vogt (1980, Astronomy & Astrophysics 88, page 66). They usually change 
between 2 or 3 supercycle lengths. At that time was only, however one 
mean length known for WX Hyi: ~142 days.
So, whether WX Hyi switches between different supercycles length would be 
an interesting question.
