Thanks for the time. (I never read the 2nd Knuth book at Univ. :-) ) OK, obviously the obfuscation algorithms using entropy are equivalent to some form of hash

Thanks for the time. (I never read the 2nd Knuth book at Univ. :-) ) OK, obviously the obfuscation algorithms using entropy are equivalent to some form of hashing/encryption function. So if I understand this: To just keep every Xth bit (where X varies over time) of the generated data doesn't help (it adds a little obfuscation to the algorithm?). And to combine multiple algorithms with their own sources of entropy is not superior to e.g. just using the three entropy sources to get better data?
