I honestly wouldn't be too upset if they did try to spread out the promotion over a longer period of time in the future, ditto with the PV releases. With 7 groups (including a part-time Country Girls), even if they all only released one physical single a year, you could keep things spread out enough that there's always some hype for the primary releases while still being able to have digital singles released throughout the year. As a hypothetical example where only two groups get a physical Triple A side in the year:
Morning - Triple (Fall/Winter physical release)
Tsubaki - Triple (Winter physical)
Kobushi - Double - (Winter/Spring physical)
Ichioka - Double (Spring physical)
Juice - Double (Spring/Summer physical)
Angerme - Double (Summer/Fall physical)
Country - Double (Special/Holiday digital release)
You end up with 14 songs from physical singles and 2 digital songs at a minimum. They could effectively have long promotional periods with only slight overlap between each group, and average releasing just over one PV per month from physical singles, not counting any short PVs from extra digital singles. Since the optional digital releases they do throughout the rest of the year require less promotional budget, that money could be used for a longer promotional period for the physical releases to increase the amount of events and exposure each single gets before release. Outside of that, if more than two groups get triple A sides, the number of "hype points" you can have during that period increases as you have more song premiers and PV releases with each one bringing more attention back to that single before the release date.
