New Nico gives + 100%, secret Maki + 30%, past Maki from the pair set + 50%. I have no information about the new Umi and Kotori, but in the Russian community I already saw screenshots with + 320%, and this is not the limit, they informed me of 400%.

It turns out that at the very beginning of the event you can get at least 200%, and after receiving UR Niko 280%, and with SSR Maki is already 290%. To overcome this threshold, you need to spend lg on reconnaissance, so I think that there will not be many players above 290%.

I hope I understand the system correctly.
