Alright, the first day of Score Match 4 is over and here are some numbers:
Score Match 4: Nico - 9 days
T1: 17.49k
T2: 9.65k
and previous events for comparison (current - previous)
Score Match 3: Hanayo - 10 days
T1: 13.97k (3.53k)
T2: 7.98k (1.67k)
Score Match 2: Kotori - 9 days
T1: 15.16k (2.33k)
T2: 7.58k (2.07k)
Going to give KLab the benefit of the doubt and say they are using Nico's event to see if Umi's was a fluke or not. I'm probably not gonna go for T1/T2 until Rin or Maki's event. Hoping tiers will be increased by then.
