Ever tried a piano lesson? Good luck actually playing better after than before the lesson. Its the endless hours after the lesson which gave you an understanding of what you are trying to do, before you will see that actual improvement.That's just the typical crap that teaching pros spout. Only in golf do we put up with this logic. I've never had a skiing lesson or tennis lesson where the instructor says "expect to be crap at first). So what if it feels different. It should still work instantly whilst you get accustomed to the feeling.
Golfers are so gullible
