Comment on Significance of Compression Rate Method

First of all, compression doesn't have to be limited to just commonly occuring sets. For example, if I create a fractal, you don't have to find out commonly used colors or pixels that occur near each other, but just create a program which generates the exact same fractal. When you do this you add another element to the system - time. How much time do you spend trying to compress something, or vice versa, decompressing it? And no compression system can garuntee that every observed instance can be compressed to less then its original size. Infact, there are always going to be cases where compressing it actually increases the size of the file, possibly significantly, but at least just a few bits.
