Clear as day. There are two grading standards. A 10 without subs may actually be a 9.5, or 9.... or maybe a 7.5 with subs.... Pretty clear explanation, and now I get it. Two different standards.
Unfortunately, I hate that answer. I have gotten back several 10's w/o subs and was considering resubmitting them w/ subs because a 10 w/ subs is visually more appealing. However, I'm planning on doing an SGC crossover now. I hate that CSG maintains two different grading standards and disguises them as one (under the same label, brand, etc...). It seems deceiving, and wrong.
I would've preferred an answer like "we're greedy". That would've been better than "we maintain two different grading standards and haven't told you all along".
