The more laid over the shock is, the slower the suspension frequency.

Fred said it & I believed it. It does sound contradictory until you dig deeper. Here is what I found by using mathematical calculations for finding suspension frequency. (Yes, it's rocket science. All you 'engineering' guru's probably know the formulas.)

The lower shock location changes suspension frequency more than the upper. If you calculate suspension frequency mathematically the truth comes out.

Perhaps it should better be written as-
In general the more laid over the UPPER location is the slower the suspension frequency. And, the closer the LOWER shock mount is to the chassis the slower the suspension frequency.

**tune with lower shock location; farther out = higher frequency with same spring and upper location

**fine tune with the upper location; farther out= higher frequency with same spring and lower location

It might be possible to come close to the same frequency by mounting the shock in two different locations-

Inner upper and outer lower vs. Outer upper and inner lower.

Have I confused you yet? Mathematically I found if you want the lowest suspension frequency mount the lower (bottom) end of the shock on the inner most position at the a-arm and the inner most position at the top.

I'll go edit the previous post.
