There are a lot of things we do in Total War because they seem like common sense, even though we don't know if the systems behind the scenes really back them up. I put my archers on hills because I think I remember a loading screen tip saying that raised elevation increases your damage output, but by how much? And does it apply equally to melee attacks?
Fortunately, Creative Assembly recently began explaining what goes on under the hood of Total War: Warhammer 3 in a series of blog posts called the Feature Focus series, which are doing a great job translating those assumptions into actual numbers, even if they slip into algebra at times, like saying "coefficient" when they could just say "multiplier".
