It definitely "could",but there is no GUARANTEE the KG will happen on any given night.
It "can" happen on Party nights as well as PM EMH nights.
Historically,the KG "usually" happens at 30,60,90 minutes after Park Close,but "recently",at least some of the time, they have been doing the first KG right at Park Close.
Sorry for the "non-definitive" answer,but the
KG is somewhat "unpredictable".
