In a delay type battle your overload threshold is 15% - for a 4000 point force this is 600 points - and the award is 50% of the overspend.

A German 105mm Howitzer costs around 30 points at base experience (9x30 = 270) - so not enough to give any points! Are you sure you dont have 9 batteries of guns? Or a bunch of mortars you forgot about? Units bought with support points count. Also remember Ammo units count against your artillery overload threshold.

As Jivemi points out, you may well be reading the numbers the wrong way around - I often do on the turn 1 report - check the results screen.

Personally I love the overload system makes balancing forces easier and fairer.
