One of the most important things that is left out of most computing narratives is that the early space programs had a tremendous amount of stuff pre-computed, i.e. cached and memoized through the hard work of mathematicians and physicists back on Earth. It is not like these days we don't have to run those numbers, just that our computers taken over most of what used to be done by hand. Noting the amount of human computing manpower taken in conjunction with the guidance system would give a much clearer picture.
