Or is it a mystery?

They never max out, You just get diminishing returns beyond 10. going from 4 to 5 will be a 1 point increase in the SA's effect, where going from 12 to 13 might give you 0.4 increase in effect.

The exact amount of the reduction beyond 10 is unknown, but the cost of going beyond 10 is probably not worth while most of the time.

Aura of intimidation isn't worth it at any level... proof.

No limit, but technically saying, you can only put 10 + 6x4 + 4 +1 = 39 in a SA.
I remembered Joe blitz used try it? In First Step??

Bort said anything past 12 is a diminishing return and not worth it.

Technically this is incorrect.
Bort-
Question: But would it be possible to get a rough example of how diminishing returns on SA's over 10 work?
Answer: Exponential decrease. I'd not recommend anything over 12-13 myself, but some people swear by going higher. Higher will count, but eventually it's pretty minimal.

Catch22 also stated twice that it starts at 10. Search http://www.glbwiki.com/qa/search.php for the word "Diminishing" to see all the Q&A comments about it.

You are correct though that bort said he wouldn't recommend anything over 12 or 13. Just wanted to keep the info accurate.

I still think it is funny how some people don't understand the concept of diminishing returns. I guess there are a lot of young people out there playing this game, but still...

I had someone try and tell me that the effect of Spin would be worse because of diminishing returns.

woah settle down college grad.

Yep, diminishing returns still provide improvement.

Yeah... just like the current economy.

There are some SAs that can be taken beyond 10 that show marked improvement.

This proves that kids will tell you anything!

The wise words of Dub J have spoken.

Meant to press Edit. Sorry!
