Scoring

[scorpio_rocks]

From the manual:

Your victory point score is calculated as: VP = (Total points from objectives) + (damage points scored on the enemy)
Your opponent gets the same calculation but obviously scores off your destroyed and damaged units, plus his victory hex points.
The 2 sets of VP are expressed as a ratio to determine victory. The victory result is then determined as follows

• decisive victory - your ratio of points is 8 times the enemy's or greater
• minor victory - your ratio of points is 2 times but less than 8 times the enemy's score
• draw - whenever either side scores less than 2 times against the other side.
• minor loss - your opponent scored a minor victory over you
• decisive defeat - your opponent scored a decisive victory over you

Please note that partially damaged units count, so if you do 23 points damage on a 100 point AFV, your score 23 for that damage.

So you DO get points for routing units as they are almost certainly damaged. and as pointed out you are giving away a great deal of points in the artillery overload.
