The previous trigram was accurate to the point of predicting which ten-pull would yield a reward!
Can you calculate the precise draw probability? Can you predict which ten-pull will surely give you something? Probably not; at most, you might estimate that one out of four or five ten-pulls will grant a reward.
"Guaranteed reward within fifty pulls" and "guaranteed reward on the next ten-pull" are two different concepts.
The divination feature in "Mountain Village Memories" is powerful because it makes many probabilistic and data-driven elements more precise.
So, will you get lucky on one pull, or will you have to endure all fifty attempts to secure a guaranteed reward?
No one could answer this question before, because probability is a tricky thing.
The divination function in "Mountain Village Memories" can't determine which between 1 and 49 draws will yield a reward. But it can calculate in which round—10, 20, 30, 40, or 50—you'll get one.
Of course!
