Producing an equivalent result in less time than a less capable engineer is not the main benefit of having some really good engineers, at least not at all companies. It's being able to perform work (and well) that requires more knowledge/ability. I know quite a few people who can't be replaced with 2 average engineers, but that's not because they work at a >2x faster pace, it's because I wouldn't trust an average engineer to do their job.
