Covert and Assassin bonus

Are they both tied up to the same bonus?

If i choose to change my bonus points to covert, it raises the assassin bonus aswell? I`m asking this because of this:

Stat Base Value Basic Techs Custom Tech Bonus Personal Bonus Total Power
Strike xxx 100% 0 a% yyy
Defence xxx 100% 0 b% yyy
Covert xxx 100% 0 c% yyy
Assassin xxx 100% 0 d% yyy

I see on the "Personal Bonus" column that you "could" get a bonus for Assassin, but in the change rase/personal bonus page, you can only have bonuses for:

Attack Bonus (1 Point equals to 1% increase in attack)
Defence Bonus (1 Point equals to 1.35% increase in defence)
Covert Bonus (1 Point equals to 2% increase in covert)
Income Bonus (1 Point equals to 0.125% increase in income)

I`ll ask this complicated question into a single simple one: Covert bonus=Assassin bonus for the "covert" rase or for personal bonus points?

No, the "d%" you pointed out was left for aesthetical reasons.
Currently it's impossible to get a personal boost to assassin.

So bottom line Personal Covert bonus ≠ Personal Assassin bonus.

However the covert race DOES get cheaper assassin skill upgrades

Thanks for the very good answer.
