2 Questions/Observations about TPG Grading

[perezfan]

Probably obvious, and likely already discussed ad nauseam...

But could someone please explain the following discrepancies, regarding TPG Grading...

1. Why is there such a giant span in acceptable condition for cards graded 1,2,3 and such a miniscule difference for cards graded 8,9,10? Why not make the grading increments equal for each numerical progression? The condition variance for a PSA 2 (for example) can range from a totally destroyed card, to one with barely perceptible paper loss. On the high end of the spectrum, the differences between an 8 and a 10 are barely visible to the naked eye.

Why and when did people start collecting this way, and why is a ridiculous premium paid for something you can't even see without the aid of a loupe or microscope? I'd love to hear from somebody who puts complete faith in the hands of TPGs, and actually collects this way. I know most people will say it's "The Registry", but how did it become a hobby for only the most extreme OCD? Is it pure ego?


2. There are apparently two separate factors that go into determining a card's numerical grade...

A. The condition of the card, i.e. the amount of degradation due to handling, exposure to the elements, etc. This includes wrinkles, creases, surface and corner wear, etc. I get this.

B. The centering of the card. This has nothing to do with the condition or handling. It is how the card originally came off the presses. So why do they penalize cards severely for poor centering, and not for more serious issues like focus, registration and color? Both represent the original traits of the card. So why is poor centering such a crime, but much more visibly distracting issues are completely given a pass? To me, the image on the card itself is the most important factor, yet is never factored into the grade.

A good example is the Leaf Larry Doby below. The focus, registration and color is so bad on the "6" that you can't even make out Chief Wahoo on his sleeve. Yet the grade is not impacted at all. In what world are these factors less important than slight off-centering or some corner wear?

Really want to hear actual collectors' thoughts, as it's been bugging me for years. I will not be critical of any responses... just want to understand, as I often feel like I'm living on an island. Thanks!
