Monty,
One thing I have learned is that my planer often gives me snipe at the ends of my boards so I don’t generally cut anything to length until after I’ve planed it close to thickness. If I don’t have that option, then I only plane it to about 1/16" more than I need for thickness and finish it up with my thickness sander to remove the snipe.
