Load Balance method - assign % of load to different hosts

I'm being requested to assign a different % of traffic load to members of a pool. For example, we have 3 hosts that should each take 20% of the load, and 4 hosts that should take 10% of the load, all in the same pool.

 

 

I think this can be done with the Ratio (Member) load balancing method but I can't wrap my brain around what to set the ratio to and the docs seem pretty vague (at least the ones I've found describing Ratio). Will assigning 2 points to each of the 20% hosts and 1 point to the 10% hosts do the trick?

 

 

Would any of you gurus mind educating me on what the ratio numbers mean and how I can apply that to this scenario?

 

 

TIA,
