If chance of critical impact is increased by 40 %, that would indicate that what was 5 % chance, now becomes
7 %. However, from the high rate at which critical hit occurs, I conclude that the chance of critical is increased to 40 %.
Am I right?

Or should it be : increased at 40 % chance?
I think they just add the percentage , 5 + 40 = 45%
That makes sense 
New argentinosaurus well be the most reliable crit machine ever
The increases are added onto the base value. If we take the example of Baryonx, which I’m more familiar with. It has a base Crit chance of 20%. Ready to Crush says Critical Chance + 30%, that’s 20% + 30% = 50%. It’s the same maths for Critical Impact.
