This is just observation, the recollection room in the vast majority of RPGM games are always full by the end of the game.
This game Fujino split his like this, 64 spaces to Asuna and 21 for the other girls so his math is simple to follow, the game should end with 140 to 150 scenes give or take between 7 to 8 scenes per update.
The big problem with this game in particular in my opnion is the excess of foreplay, the eternal cycle of blueballing, ok i give that can't be only sex scenes all the time, but for instance Asuna and Inoda had their first sex scene in the tree house update 0.40, 8 months for that. Asuna already have 37 scenes and only 4 sex scenes with Inoda 5 if you count the FOG rape that's why i said too much foreplay, even Sugu had more sex scenes than her.
