So, has anyone else been following Royalflare's DDC demo scoreboard? A lot of the categories aren't very polished yet (you can tell because I took the lead in nearly all the Easy and Normal categories without much effort), but there are a few that I've found pretty impressive:
Lunatic ReimuA. It seems ReimuA's bomb can also be used for supergrazing, as shown by a gain of over 10,000 PIV from Cirno's nonspell. The rest seems fairly polished as well, though 未知 (in-game name ns) keeps improving it.
Lunatic SakuyaB, currently the overall record of 320 million. Mainly due to the survival involved, since SakuyaB is a very weak shot. The bombing route is also rather different from Easy/Normal, since some early patterns are actually worth a lot of PIV (as some players here have demonstrated, I think ななまる (in-game name NANA)'s route is the same as Majildian's but with all Kagerou spell bonuses).
SJF's latest Normal SakuyaB record of 268m is the first to spend every bomb on Sekibanki (a route previously used on Easy but not Normal), gaining 8,000 PIV but requiring much riskier stage 3 auto-collecting. The stage 1 route could be improved, though; defeating Cirno in the 3rd wave seems better than the 4th (more power items from enemies, meaning less unfocusing necessary to reach 4 power by midboss Sekibanki), and I regularly finish stage 1 with 17,500 PIV. But it's still a good score.
Easy SakuyaB still remains as competitive as ever, with 3123's latest 218m 221m using a different route to gain two additional x2.0 collections in stage 2, for an additional life to use on Sekibanki, finishing with 96,130 97,580 PIV. And that's with rather inefficient grazing on stage 1 (my 212m gains 700 PIV over 3123's, without sacrificing any of the 2nd spell bonus). Interestingly, 3123 also supergrazes Sekibanki's 1st boss spell by circling around the head, gaining ~400 PIV at the cost of 2.5m spell bonus. I guess that's actually worth it?
I've also noticed that Normal ReimuA has been steadily increasing, and ARF's Lunatic MarisaB score is no longer in the lead.
