Basically what OP is pointing towards despite his strange numbers, is over saturation... More coins and not as much demand equals low value.
It is this simple, and there is no need to make overly complex assumptions. Roughly 3,600 new coins are created every day. There must be demand for 3,600 new coins every day for price to stay steady. We just fell off a period of massive amounts of panic buying. Most panic buyers have sold out at this point. However, for price to rise again, we're going to have to wait for more infrastructure and useful functions to come out of bitcoin. And they are coming. Patience is a virtue.
