Suspension Geometry Discussion

When you guys are building an unequal A-Arm Suspension (front), what numbers are you shooting for and why?

I was told to stay as close to zero anti-squat/dive while keeping the number a positive one. I do not know the reasoning behind this though.

Pointed towards a long travel set up. Mostly slow speed rocks with some high speed jumps and whoops.

From my understanding, anti dive resists the suspensions ability to let the nose dive. At 100% anti dive the front end should stay level during braking and not move up or down. A high anti dive such as 150% will cause the front end to lift during braking and a low value such as 50% would cause the nose to dive under braking. (Not actual values, just used to represent high/low/median). Is this true? What actual values are guys running on long travel prerunner? Why? E
