I had a look earlier.
It actually allows you to generate a final league table without supplying any predictions. Results are "forecast by the calculator based partly upon recent form, although note that there is also a random factor built in to simulate the unpredictable nature of our sport."
So without any input from me, the calculator says we’ll end up on 82 points, with Arsenal on 79. Apparently we’re dropping 15 points in our final 11 games. That is f***ing random.
