To update this, my long, long run of extraordinarily bad luck did finally end. Since then I have had some undoubtedly very good luck, and returned to the top 10 in the league.
It seemed to me to be absurdly improbable, although of course a long run of bad luck will almost certainly occur if one plays enough games. Unfortunately there is no practical way of determining just how unlikely my run of bad luck was. So I just have to leave it as anecdata.
