The question of how many rounds to use is decided by semi-automated cryptanalysis. (Note: the SHA-3 candidate version of EnRUPT in stream hashing mode was insecure. The current block cipher mode is insecure. There is a minor change (use a few more rounds) which is thought to fix the stream hashing mode.
