Ah ok, haha, but consider that most of these games run on a clock based RNG, if you happen to be rolling on a sh*t block, you could end up with 1000 bronzes. I know I've had it happen to me on Aigis... back before I understood the concept of time-referenced RNG.
That's why I always test the block period using a cheap gatcha like 2k rolls before I roll premium rolls. If I'm rolling 10 irons in a row, its a stupid time to be rolling premium.
For Aigis, it seems the reference period is about 30s-1min, and the block period is about 10 mins or so. That's what I believe at least since my experience holds it to be true.
If you roll a black or plat, keep going as fast as you can until you start rolling 2 silvers or more in a row is my strategy, so far its netted me 5 blacks with my 30-40 rolls over the last 8 months.
I'm not sure about FNK's RNG block periods, but it is almost confirmed to be clock referenced
