If what you posted is correct, you didn't go more than 8 hits without finding an item or a medal, and that was a lot of hits. I consistently got 20-25 or even 30 hits without seeing ANYTHING, and then all the sudden I will get 6 medals in a row. It is kinda odd how I haven't found any items from valleys yet, I have made more than enough hits to where I should have gotten something.
