What does this Crit formula do?

[Rink27]

Formula:
rate = (user.cri + (user.luk/100)) * (1 - target.cev - (target.luk/100));

I'm using Yanfly's Critical Control script to edit the rate of crits.


I've added (user/target.luk / 100) to the equation. In the scenario that the enemy has 100 luk and the right side of the equation becomes a negative...
Example:

0.5 * -0.1


= negative rate


What happens with a negative rate? Is it still zero or would irregularities occur?

Critical rate is your % chance of getting a critical hit. In theory, if the chance is negative, it should just be treated as impossible by the system, though some plug-ins do floor the percentage at 0, so it would just treat that as a 0% of a critical hit in the end.
