So you discount a possibility that the controversy and allegations against him had at least some effect in him playing worse in the Sinquefield Cup?
Anyway, there were studies out there that there were no statistical differences in his rating gains in tournaments broadcasted with delays and without it. Study by Kenneth Regan also found no irregularities in his play, so the only 'evidence' of him using computer help are allegations by a company that is in business relationship with Carlsen, and his 'bad' analysis in post game interview. I'm not very impressed.
