I believe that Sienci just put out a video about this topic yesterday. If you went and bought a router and bit so that you could put a decorative edge on a project would you be overly concerned about how fast you are going to pull your new router and bit across your piece of wood? I would submit that the answer would be probably not. Of concern would be that the finish be smooth and not have burnt spots. The issue of feeds and speeds has been around since the invention of machines, drills, lathes, milling machines, and more recently CNC. This was due to needing to find the highest production output for any given process that would meet the QA for the part being machined along with achieving acceptable tool life. With our hobby machines we are interested in achieving essentially the same goals. We want an acceptable finish, QA, and we do not want to be purchasing new bits every time we do a project. All feeds and speed tables for hobby machinists are in my view, and many may dissagree, a baseline starting point that are subject to change by the operator based on knowledge and experience, and possibly the desire to get a job done more quickly. In a productioon environment knowledge gained from thousands of hours runtime will dictate the feeds and speeds used.
In conclusion I would say start by following the feeds and speed tables and as you gain experience you will find what works for you. Heat is your enemy, make chips not sawdust, and your machine will let you know when you are pushing too hard.
