The schedule is the absolute authority in the game, all the numbers there are correct as to the amount of content currently available...with the exception of the 12 girls, which is a known bug because of how "Multigirl" is listed in that same list. Any villains that have "-" listed means they have nothing, as opposed to "X" which means you haven't done it yet.
Ah, the - versus x is very useful to know - thank you!
So now I need to try to find that missing villain (the last one on the list, unless the laptop always displays ??? villains last). I have a fuzzy memory of my previous playthrough, on 0.24b, finding a villain I haven't found yet here. Unfortunately I don't recall much; I need to see what I can find....
