In practice, for most of the materials cut on a Shapeoko, there is a wide range of acceptable SFMs, so RPM could initially be chosen pretty much anywhere within the router's RPM limits (10k to 30k for the Makita/Carbide router, 16k to 27k for the Dewalt router, and typically a few hundred to several tens of kRPM for spindles) These router bit fall short in terms of longevity.

Under ideal conditions it is usually suggested that the actual feed rate be set to approximately one-half the calculated amount and gradually increased to the capacity of the machine and the finish desired.Once you have determined what feed and speed to start with, there are other factors to be taken into consideration.

The feed and speed is the same, Im taking shallow passes as I would with surfacing and the cut duration is also similar. I would use an end mill (which is good for plunging) and a high speed. Therefore depending on the diameter of the tool, if the RPM and number of cutter edges stay the same chip load will increase with a larger diameter cutter, thus the feed rate will also increase. There are many different ways to program any job, but this method is a catchall for small parts and a good finished edge with no tear out on a vacuum table with a spoilboard.
