Miracle Time Possibly Rigged?

0 * 0 = 0.
2 * 0.00001 = 0.00002.

When the rate is abysmally low, expecting "double rates" to actually mean anything is just plain foolish. Not saying that the rate is literally 0.00001%, but it's so damn low that multiplying it by 2 does nearly nothing. And that's the point. Saying, "Double your chances!" is way better than saying, "Add 0.00001% to your chances!" You expect "double" to mean a lot but it's proportional to what it's doubling. If it's doubling nothing you're not getting anything.

Yes, there are people who get lucky during Miracle Time, just like there are people who get lucky during Normal Time. It doesn't prove or disprove anything.

I'm not sure why this is a surprise to anyone. It's a marketing scheme and anyone who says they spent over 100k NX and got no better results than the last time they spent 100k NX got played.

Maybe there is more to this than just a marketing scheme.
I recall a lot of people in past threads saying how good black cubes were, but now it seems they are worse during supposed 2x miracle event than super cubes used to be without an event. Perhaps for the first month after they were introduced black cubes did have better 'introductory' rates, but sometime before this event the rates were cut by a factor of 4, so that even with the miracle event (assuming it even worked on black cubes) they still had worse rates than initially. There have been many times in the past when drop rates were lowered or something was 'accidently' broken a month or two after some new boss was introduced. This sounds like a similar trick.
