War score averages

There is obviously something wrong with calculating war score averages. We are at war with a load of Japanese cheaters for the second time in 2 weeks. Their top scorer in the last war scored over 1 million points and hit my team with over 320 magnetism alone. This week the war has only been going on for a few hours and he has already scored over 400k. His war score average is 25k. How can this be correct? Others in the team have 60k average and scored 220k this week and over 400k last week. Most also have level 20 magnetism. 
Their biggest cheater was reported 2 weeks ago but nothing has been done. I have reported it again but not holding my breath!
