My tip is just to not waste too much time being frustrated by this flawed game mode.

Here's how to guarantee an Elite 2 finish every week.

Play all matches on amateur or semi-pro.
Score 5 goals in the first half.
Put your controller down in the 2nd half and go do something else.
Collect your 800-ish points.
800 x 40 matches = 32000
+ 3000 from TOTW and Featured = 35000.
That's enough for Elite 2.

If you want to take a little extra effort for Elite 1, do the super bad squads on WC or Legendary.
