We all know by now that you need:
5,000 FP + 5,000 PP for 600 rapids
50,000 FP + 50,000 PP for 6,000 rapids
But this is what not many people know:
There might be situations where you have a lot of FP but not PP resulting in you not being able to recharge rapids.
I wrote a support ticket to RS with questions about converting points and the girl offered me to use the old rule (10,000 FP) and credit my account for 10,000 FP.
If you're in a similar situation and you want to optimize the recharge of rapids, just write them a email and ask them to convert for you.
