There is no meaningful variation in the sub increase. As you can see from ID1, ID2, ID3, ID4 the Cover requirement is basically "get 1 million subs and a new gen will happen.

Each of them with a million subs leads to the next generation.
For Stars the threshold appears to be 100k, hence a Tempus3 is more likely to happen now than a HoloEN2, paradoxically. Perhaps this will be amended to 200k.
JP7 will come as soon as Chloe reaches 1 million in about 2 more weeks.
Holo EN3 is unironically more than a year away, summer 2024, because IRyS and Kronii are lazy and their retarded fans won't sub to the other girls in Councilrys because they are mouthbreathers.
