Drop Rates

Just curious if 3000 to 5000 boxes should have yielded at least one Pred trophy? It seems I get the same red shaders for the same guns and Pred masks multiple times. The algorithm appears to be off…

the drop rate of a yellow item comes out roughly to .2% so do that math friend

I just figured reds seem to be about 2-4%, and the animal skulls are red rarity. Dunno just seems off.
