I have learned that as you gain experience, there are many times you don’t want a board to be perfectly straight. For example, gluing up a panel with tension in it will help it last for lifetimes without splitting. A jointer set to get a perfectly straight edge most likely will not do it on a regular basis and the board will more likely than not have a convex curve in it. I used to adjust mine so a very slight concave curve resulted. Another example, A bit of curve on a hand plane blade is useful to speed removal of rough surfaces and slight (<.002> concave edge for edge gluing.
Agree with those above. Perfection is not needed everywhere, just in the critical areas. Like finishing a house…the only two places perfection is needed is in front of the toilet and around the front door!

BTW I’m happy if a 10” blade wobbles less than .005.
