I think it's been mentioned, but your bonus to allies, (which is what you look at when calculating combined stats) is only 2% of your raw stats.
N8n8 you stooopid. 100,000 stats on an ally that you buy will add 2k to your bonus to allies, which is what everyone sees. Just take whatever you see on another's profile and multiply it by .02 and that's what adds to your bonus to allies. just repeated myself twice but what the heck, who cares.
Essentially. 2% of your BFA figure for a set stat is what you actually get as a 'static bonus' to that stat.
So the bfa adds up to your raw stats but later if you want to know your new bta you'll have to convert it by multiplying your raw stats plus bfa by .02? Like equipment? Invisible stats?
No. Your BFA does not add to your BTA. If this were true, then it would be like a chain of power going all the way up the LB. If this were true, you would inherit the strength of all your allies' allies' allies' allies'. Your BTA is based only on YOUR stats, not you plus your allies' stats.
Your BTA is 2% of your raw stats, which I posted a picture of mine. If you were to hire me you would get 2% of that as a BFA. On your profile page it has your BFA in the same section as your BTA, but your BTA is only a portion of your actual raw stats. It is not added into your stats and only benefits your owner.
Raw stats is the actual attack/defense strength of your kingdom. They are often overlooked because you are the only person that can see them. Everyone deals in combined stats (BTA) because everyone can see what they are.
Look at the pic I posted on page two. I am at about half troops so you can see my attack and defense strength is about half of my max. Don't think too hard about it and it will make sense.
