I suppose you could argue that technically since we drew one match with Celtic away then for our home record to be completely analogous we'd only be a couple of points behind them. But he's not correct, we'd still be third. And in a year when we've been fortunate to face an historically bad Celtic team, which in itself is a slice of luck.
The whole premise of this argument is a bit silly though. The season has been a success even on the terms that The Family himself (or herself) set out at the start, s/he's just moving the goalposts now.
