What is Max Special Points?

To start, I have 58 special ponts. I see in spec build planners the max is 56. So you start with 7, and get 49 from leveling to get 56 max. So I have 2 Xtra points for some reason, i can't remember, its been years.

Also, I'm leary of using the Special layout system because I don't want the game to eat my 2 Xtra points.

Any explanations would be appreciated, thanks.
