Where's Lusche?
I'll tell you this much friend....... The scoring system is crazy.
But keep in mind, because there are 4 different categories, it is possible that 1759 people have better scores than you through the combined rank simply for upping each category..
You have not up'd a gv this tour. I know this because of your rank. Many people have that rank. That number 1612, reflects that only 1611 people have up'd a gv. You, and 3000 other people have that 1612 rank.
And no Attack sorties either.
Up something in each category and check it again tomorrow. No matter what happens in your sorties, I'll guarantee your ranks will drop.
