From my own (&my friends') experience, the background RNG is like a wave table, many things you do, you are advancing on the slopes of the waves, if you pull at the peak, chances are you'll get golden card, of course there'll be random sparks on the low position when you'll still get golden.

What's difficult is how to determine where you are. That's why people use FP in advance, if the result is good, say two or more 3-star cards, especially if the 3-star cards are the last pulls, it means you're advancing from low to high on a wave, so turning to qz pull likely get you golden. Same thing if you're getting many red chests from the enemies in last arrow (as long as the red chests are not guaranteed). Continue to pull or fight advance you from the peak down, so you'll need to force another wave to appear by FP or fighting etc.

By Great/Super success you cannot guess the wave, maybe it's on the peak or maybe it's just a random spark on the low position. Logging in different times seem to give you different overall wave pattern to begin with.

Of course, there's a speculation that some accounts just get SSR far easier than others, one of my friends has two accounts, the JP one just keeps pouring in SSRs while the NA one has only 2 from the launch and have't seen even one since then, and both are on the same device.
