Man, go to bed and wake up, what's waiting for me?
EN event: Barely in the top 200 when I go to bed, just slightly out of the top 200 when I wake up.
JP event: Climbed up to the 890s before going to bed (required 2x 1st places and 1 x 2nd place in the EX songs, plus a 4th place). Wake up, in the mid 150ks.
Now, I know that most of the EN players were asleep with me and that's not fair, when the JP event just started and the bulk of the players would have been all awake while I slept, but still...I don't think there's anything I can do that would make me drop over 150k places overnight in the EN version like that.

Gotta spend the stones if you want to hang in JP.
Edit: Looks like Rin is running slightly slower than the Umi event, primarily because of the bump from 25,000th place to 30,000th place being the cutoff for the 2nd SR card. Very rough estimate of 64.5k needed for that 2nd card. Don't let the number scare you; Score Match scores WAY higher than token events. It feels like I use the same amount of stones to compete in each event.
