And your basis for the cadence above is what exactly?
There is no set cadence for these events. Usually we see intervals of about 90 days, but that is approximate and can have a very significant variance.
As mentioned by others here, there was Bo who got returned every month and we've had JarJar who returned after 113 days, there was JKCK who had one instance of 147 day wait, Grand Inq who had a whooping 184 days wait for first return and then returned second time after 91 days.
Our expectation is 90 days (nothing about monthly) but reality is that nobody know when Baylan will return, so best advice is to just get ready and then hope for the best.
