The points are not 100% accurate because the wait time can vary even for the same donation given. That donation was set at 2:00 because someone stated they gave that and got a 2:00 wait time. For me, this was on page 3 first post.

Dropped in 2 Pero Puddings, 1xPeronamin for silver button, 2 hour timer which gave a card reveal.

I will see about testing this donation a few times and see what the timers come out to be. Or if someone can help me with that since I don't have any of either item left right now.
