Sorry you aren't happy and I hope you get it cleared up. Here's what I learned from your post. Based on your past experience with PSA, this indicates to me that CSG 9.5s = PSA 10s. Understandably you're probably concerned about value of a CSG 9.5 vs. a PSA 10, so it's good that you're sharing your experience so that ppl start to understand this.
If you've got CSG 9.5s you think are PSA 10s, then it's important to price them as such and inform your customers/buyers of your experience. It's data like that which will help communicate to everyone how good a 9.5 from CSG is.
As a side note, this makes me less concerned that CSG will have to engage in "population control" like PSA, i.e. "oh shoot we gave out too many 10s." So there's that.
