To paraphrase the article, Ken Regan thinks that someone's chess skill improving too fast is conclusive proof that they are cheating.
I'm not sure this is really a true analogy to the examples of catching users of performance enhancing drugs; it would be more like saying 'your time on the track has improved by too much for us to believe, so you must have cheated, and therefore you are disqualified'.
Perhaps it would be better to use his software to target people for higher scrutiny, rather than as categorical proof of cheating. Cheaters, however, could just make sure that they always cheat, and ratchet up the search depth at a rate below the maximum permissible improvement rate.
