Triple Throw 30.

This is what makes my theory solid. The idea is that the server has a ticker on it, and every time a certain kind of scroll passes, the server keeps count. After six 60% scrolls pass, it allows the next four consecutive 60% scrolls to fail. This would, by technicality, make them pass on a 60% success rate, but instead of putting more load on the servers to make them do random calculations.

If you scroll in the day, then, it would be more luck than statistic. If you think about it, the counter on the server would be changing far quicker than at the non-peak hours. More people are online during the afternoon hours, meaning more scrolls are being used, thus making the ticker on the backend progress more rapidly. This would raise the "luck" factor of it.

However, in nighttime hours where the servers are desolate, the counter would, obviously, progress much slower. This makes burn scrolling effective. You find the sweet spot where you've exhausted the failures and then continue to make use of the server's passing slots.

It's all in the wording, and if anything, it would explain the crazy outcomes burn-scrollers are able to achieve. I can attest to this also, as every single +6 or better equip I've ever scrolled as at night. Yes, that's a bit of a blind statement to make, but whenever I scroll in rapid succession during peak hours, my successes are spread far apart comparatively.

I think you are seeing Shadows. You should go roll two dice ten million times and write down the result. I can already tell you to within less than +/1 10 the number of times you will roll each number. That is how consistent the law of averages is. I don't know if it is understood how it works, but it does work. Nexon doesn't need a special "clicker" to keep track of what passed and what failed. The law of averages averages it out for them regardless.
