BrianI bought a lot in May from Mastro with 103 raw cards and 36 cards SGC 80+. 32% fewer Ex and better than advertised (said 88, I got 60 from SGC); 138% more Vg/Ex than advertised (said 8; I got 19 from SGC); 143% more VG or lower than advertised (said 7; I got 17 from SGC). SGC also refused to holder four cards.
Granted, this is a single lot & very small sample size. That being said, any collector could have seen the 15+ cards in the lot with significant issues. I find it amazing their own submission of 36 cards to SGC was spot on, yet their grading of the raw lot left so much to be desired...
Based on my experience, I would expect 1 grade less in total than advertised on the raw cards.
