Hypercount is one of my most used special abilities. I can almost instantly recognize and count 5 of something. Each time a new object is added in, it takes twice as long (generalized - not always true, but considerably close - more around 80% longer). By around 12 objects, I'm better off counting objects one by one rather than using my hypercount ability. To count 12 of something using it, I often need about 12 seconds or so.
