They have changed more than once which stats are visible to whom. It's not like Gree tells us anything so we have to figure out on our own. It's been my belief that the stats we see are un boosted and the battle results I see seem to bare that out. I do not know for positive though.
I lost to someone today that was 2.1 mil below me and I have pretty decent attack points.
They have 9 mil so unless you have over 11 mil no wonder you lost.
Considering it is fairly well known that the windows don't show stats over 10 million correctly I didn't think I needed to state that my attack is 11 mil. Wait actually I did when I said they were 2.1 million below me.
