It's correct if you take "without branch prediction" to include any pipelining of instructions after a branch. The very first branch prediction algorithm ("predict taken") is to simply enable pipelining by assuming the generally more likely branch. >...this seems to be assuming that 100% of branches are guessed incorrectly... Rather, it's assuming that 100% of branches are not guessed at all.
