The SPF calculation has a delay of approximately 15 minutes to be shown in the gui.

It takes your posting, voting and commenting activity into account but has a cap within 24 hours.

I can't read the backend, that's why I have to do excessive testing.

I am already able to let every crafting item drop as often as I want to... by manipulating it via javascript, but I have no idea how to force weapon and armor drops.

I wish you the best for the next fights. I bet you will win from now on :D
