A calculation of hags per-game. The number of female characters over the age of 24 with a portrait, divided by the total number of portraited characters.
A separate expression that weighs characters who are possible party members, and/or romance-able (see: IS Taurus dungeon choice, and nusona "fade to black and spend a long while" social links), higher.
P2 and P5 would probably have the highest scores.
