Aaron, greetings I am not a real woodworker but I know from hand routing experience that too slow a feed gives burning especially on endgrain of hardwoods. You need plenty of chips flying off because most of the heat from cutting is carried away by them.
I think you need to start from the manufacturers feed/speed advice for the tooling and materials you want to use to set the required max. cutting speed. Rapids can affect the length of a job too of course but not the quality.
