i think ive seen 50% a total of 2 times, 1 during holidays and 1 not
I'm fairly certain it's based on how garbage the events are. You'll most likely always get it in holidays, but the one other time we got it the events were just god awful.
They probably raise/lower it based on how good the events are.
I guess they consider tomorrows events kind of decent (probably because of ultimate charge).
If they were really good events we'd probably get the base 20% only.
Either when Kirio came out, or the turntable right after her. I Distinctly remember there being a 50% rebate during turntable, and IIRC, we have never had turntable + holiday at the same time.
