knowing where the entropy is coming from and knowing the amount of entropy is the same thing. it is because we don't have a way to measure entropy. we can only infer the amount from theoretical models. the output of RC4 (or any other stream cipher) appears totally random for any practical analysis if you don't know the key. therefore this sentence: >I was actually surprised how uncompressible the timedelta stream does not make any sense. the result of a complex recursive chaotic calculation always appears uncompressible, unless you know the proper underlying model. trying to compress it only puts an upper limit on entropy, but never an estimation, let alone lower bound. > 4MB/s is the entropy rate from the internal perspective of Enranda.
