Just as an exercise, I looked up Sambuev's CFC and FIDE ratings. The gap is narrowing. In May 2011, hir CFC rating was 2753, and today it is 2727. Meanwhile his FIDE rating was 2515 and now it is 2571. So the gap has narrowed by 86 points. I know that this is only one person but it is one indicator that things may be improving.
