No actually, that was based on the current stats at the time compared to previous patch stats, or else it wouldn't have been a valid analysis. If they say it's not a stong correlation then that means it's continuously not a big factor patch to patch.
I can appreciate these war reports but seriously think it's a wasted effort on the game at its current state. I'd reccomend doing this maybe when the game is...good? You're doing great but you're like a great reporter doing a report on a confused and dying snail trying to cross the sidewalk. The balance has been just all over the place with things that didn't need to be touched being rough handled awkwardly and broken things left unchecked, and it would reflect that in the MS paint world map.
nice thing! I planned to do this too, made everyday some shots of the map but since launch i'm not really playing... all in all nice thing!
