I think, in the BCCG example, that starting their grading scale at 5 and ending at 10 is what puts people off about it. If they did it as a 1-5 scale, and it was the only scale the company offered, it might have worked. But the fact that BGS and BVG have 1-10 scales, and BCCG has a 5-10 scale which replicates the higher grade #s with lower graded cards, people were bound to hate it.
BCCG 5 (BGS 1-1.5): Poor or Better <---Still no delineation in a Poor/Fair Card: one pinhole or completely trashed?
BCCG 6 (BGS 2-2.5): Good or Better
BCCG 7 (BGS 3-4.5): Very Good or Better
BCCG 8 (BGS 5-6.5): Excellent or Better
BCCG 9 (BGS 7-8.5): Near Mint or better
BCCG 10 (BGS 9-10): Mint or better <--- why do you need "or better" on Mint in this case?

Plus, people want to prove they have the best copy, and pay more to get it. That's why BGS has added grades at the Top end, and SGC has added more too.
PSA: Mint 9 and Gem Mint 10
SGC: Mint 9, Mint+ (9.25?), Gem Mint (formerly 10, now 9.5?), Pristine 10
BGS: Mint 9, Gem Mint 9.5, Pristine 10 (with one 9.5 subgrade), BLACK LABEL 10 (all BGS 10 subgrades)

One of the scandals that started on blowout recently is that a former employee has gotten about A QUARTER OF ALL BLACK LABEL cards in the past few years that have shown up for sale on eBay. Regular submitters who have mailed in thousands of brand new Gem Mint cards might get 5 Black Labels in 1000 cards, while this former employee *either through fraud or subconscious bias by the graders he knows and hangs out with* has submissions of 25 cards where 22 got BGS 10 Black Labels (perfect 10 subgrades).

Here's where the modern market is right now:
Say a card sells for $100 as a BGS 9.5 Gem Mint. It might be $150 as a PSA 10 Gem Mint. It might be $250 as a BGS 10 Pristine. It might be $1,000 as a BGS 10 Black Label. So for an almost indistinguishable improvement on a card that just got cracked from a pack made months ago, the card is worth 7x the PSA 10 Gem Mint price because of this Black Label.

Whereas the price differential between Poors and Fairs is really not all that much, and nice looking Authentics may sell for more than either of them.
