Quite a few times. Cardiff losing today, Middlesborough drawing today, Ipswich hammering the Hammers midweek. Middlesborough losing to Coventry and Burnley, back when you were top, West Ham had the chance to go top on consecutive weeks iirc after you had failed to win, but results went in your favour.
But when you dont win due to luck it kind of counter-acts the positive effect of the very thing?
