Ability to cap performance of backup units

[◄Chuck►]

A new command that the cop actively needs to opt-in won't work imo as it is more complicated than the normal backup call. Why would someone go for the more complex thing, especially when already under stress in chase?

I could think of a points system:
Idea 1: (Growing points)
Lets say, depending on the suspect, you get backup-points. For example, 1 per second for a slow suspect, 3 for a fast suspect, etc.
And whenever you call backup, the joining cop uses some of the backup points.
So imagine you have collected 100 points and call backup, only a cop worth 100 points or less could join.

Idea 2: (static points)
The number of points would be fixed and set by the type of suspect. The points set the level of cop force that may be in chase at any moment in time.

Example: Suspect FXO = 1000 pts, so you can have 4 cops with each 250pts in the chase at the same time. if 2 cops lose contact, you gain those 500pts back, and a faster car ,i.e. with 500pts, or maybe 2 slower cops may join again.
