The RP will likely count for very little in the end and what will count more are the various flags in the code for certain moments.
For example, choosing Maya or Josy in Ep 5 may count as 1 point in either direction and more choices like this will accumulate points for each girl. In fact, the walkthrough mentions that, for the Maya centric path, you have to stay with her in Ep 3 but if you skip that but stayed with Josy in Ep 2, then that couts towards the Josy centric route.
So these markers in the code could make it look like this:
- Ep 2, stayed with Josy = Josy centric +1
- Ep 3, stayed with Maya = Maya centric +1, Josy centric -1
- Ep 4, sleep with Maya = Maya centric +1
- Ep 4, sleep with Josy = Josy centric +1
- Ep 5, went with Maya = Maya centric +1
- Ep 5, went with Josy = Josy centric +1
If this were the case, my score would be Maya 2, Josy 0. But there could still be ways to balance it, like going to Quinn in Ep 3 to negate the loss of the Josy point, or there might be more decisions that give points to Josy to even it out.
