Any updated settings for corners? My team underperformed when I used the settings above.

My team:
Average team length: 5th out of 16
Heading: 13th out of 16th
Jumpong reach: 2th out of 16th

Attacking corners:
1 goals scored in 30 games. Joint 11th out of 16.

Defending corners:
5 goals conceded in 30 games. 15th out of 16.

I play a tactic with three central defenders and one striker with 19 in jumping reach. So i feel that I have good players for scoring at corners.
