The answer to that imo is down to to top 6 and competition there.
The mark has fallen to approx 35 now, if the top 6 are fighting to the end and theres a genuine title race then the available points drops for everyone else.
Two side on 90+ and another in the 80s with 2 or 3 more on around 70 would mean like last season 35 would be the mark.
Imo to get that Everton need to get goodison rocking and influencing refs. They will get 9 games against **** teams at home. It's going yo be that simple. 9x3 = 27 so they only need 3 way wins or whatever group of draws to get there.
But you've got to win at home, both defend well but must score
