That walkthrough mod, BTW, looks misleading to me. Since the [Astrja +1] and [Astrid +1] only come from temporary values (as I said before), they should have something more like [Current Event: Astrja +1] or whatever. These aren't standard points, so aren't as helpful for tracking things. It's also unhelpful that it shows the bonus for each girl in this case, because you can't gain affinity with Astrja during this event anyway. If you can only benefit from one particular set of points during the event, a proper walkthrough should only highlight the way to get the eventual benefit. The WT as is apparently just says, "Hey, I saw something in the code!" and highlights that. In most games, that would be fine, but this game requires something more involved than that.
So, I would say it's helpful for event points, but just remember that they are temporary, so you want to accrue them for one girl, and at the end of the event you get an actual permanent increase for the MC's relationship with her.
