Josh K.David,
I disagree that as time goes by, they become more accurate. I believe, as time goes by and more and more of the same cards are being resubmitted and crossed from company to company, it simply further skews the number.
T206 collector makes a valid point, whenever you cross from one company to another without cracking the cards out of their slabs first, nothing will be adjusted on the pop reports because the grading companies are not going to send flips back and forth to each other (though if they did, it would certainly help the situation). Therefore, you would have to request that the grading company send the old flips back to you and do it yourself. I asked one grading company to do that with a t227 cobb that I crossed. Unfortunately I never got it. I feel fairly save in assuming that this is the norm.
Jim B - did you send sgc the flip?
