Yeah, there's straight up no reason for Rider to change schedules. The abdication of the emperor shouldn't really matter, and the reason Decade was as short as it was was so that Sentai and Rider wouldn't premier a line at the same time. That way, they don't interfere with each others' premier and toy sales can be maximised. They're not gonna change episode and toy schedules just to be neater when this is working out for them.
