The APLT is a great way of weighting the various fixtures over a season, and as such it gives a very useful indicator of progress. I love it!
Personally I think it’s impossible to track all the variables from week to week, as you would need to write a new statistical model every week, and even then it would be insufficient. Mourinho sacked? Burnley hungover in Europe? Southampton new manager? 48 hours recovery v 72 hours? Not to mention the impact of injuries and form. And even if you had the perfect model, very weak teams and players do things they aren’t supposed to do, for good and bad.
As I type Andros Townsend just hit a 30+ yard volley in against Man City. That’s not the sort of thing you see all the time! Man City are down 2-1 at halftime, and while I still expect them to win, they have work to do and a straightforward home game has all of a sudden become a puzzle for them to solve.
I see the APLT as an overview of where you stand in the grand scheme of things, as the season unfolds, and a really like it as is. I haven’t tracked it year on year, but presumably any discrepancies with the actual table are ironed out as the season progresses.
