Yes, we're ending the batch on 324.

About the book: all the events that he prepared his StL loss with, finding info on Q-Tarou, thinking about getting Kyara as a real ally, setting up the L-file, they were all done while he had Hal by his side. And this was after he read the storybook. So it's possible that he intentionally tried to mimic the events of the book in a way, or was simply inspired by it when coming up with his own plans.
@RapidLord
Lots of different possibilities to consider indeed.
As for why Hal spared Baku I like the current theory we have of "Hal still remembers the idea of sparing people from Baku." It could be simpler though, Hal himself said that "it's better to keep people chronically in check" instead of killing them, so maybe it was just that.
And about Baku knowing Hal was the leader, my current guess is that he knew during the Bookstore Flashback arc already, perhaps even before then. Primarily because all of the actions he took to prepare for the StL loss happened during that time, meaning he must've knew Hal was the leader since the strategy of losing was based on Hal's personality. It seems like maybe Baku decided to lose after meeting him in the bookstore, and/or perhaps the time he spent with Hal was him trying to alter his personality to help with that strategy.
The main question is why Baku decided to lose in the first place. Based on his own comments (although it's hard to take what Baku says at face value), it might be something like wanting to face Hal in his strongest form, in the most highest stakes match? Since Hal/Souichi said that he would've lost if it was poker, maybe Baku was trying to reset things to pass the time until Souichi got better as a gambler. At this point I have no idea, I'm not even convinced myself that this is the right reason. Someone also speculated before that Baku might be wanting to fix or recover Hal's memory issue.
e: Just thought of a crazy/silly reason. Maybe it's because he didn't want to kill Hal for sentimental reasons, if he won. So if he wins the 2nd StL match, he can say that since you spared me before, I'll spare you this time? Although it is a bit convoluted.
e2: Going further, it could go along with that 'sparing to make people stronger' sort of idea he talked about. Maybe his goal isn't the 2nd StL, but to defeat Souichi in the 2nd StL so that he'll make a comeback and play an even more crazier match in a 3rd StL?
