Values based on sufficient experience and my numbers run very close. I'm sure you have said "sufficient" experience.
I developed the charts to jump start me on values. It quickly became apparent that there are lot of us who can use the jump start. Not a lot of people get to handle enough guns on going to develop value intuition. The charts also help focus some required learning/knowledge. If you practice valuing guns on auction sites, you get feedback from the prices realized chart after the auction.
Hope this helps a little.
