DDE 72: IW And star
[vsnet-alert 24712] probably didn't show sufficient evidence
for IW And-type behavior
(as seen from http://scan.sai.msu.ru/~denis/DDE72-ZTF-LC-2020.gif).
On the other hand, this object showed a clear "heartbeat"
phase in 2018 Aug.-Dec., preceded by an outburst from
a short standstill. Other instances of outbursts from
short standstills were also seen.
ASAS-SN data:

The 2020 behavior is an ordinary long-short pair
of outbursts often seen in high-Mdot dwarf novae.
