EIGRP Unequal Cost Loadbalancing

I thought I had unequal cost load balancing figured out until I ran into
task 3.7 IEWB Vol 2 Lab 8. The task states that we need to achieve 4:1 load
balancing. IE SG says use whatever values to get 4:1 ratio. My question is
HOW do I come up with these values? I tried a few random values but didn't
work.

Can someone explain to me HOW you got 4:1 ratio? It would be nice if its a
step by step process.

Basically the topology is something like this

R4

| -

| -

| R1

| -

| -

R5

|

|

|

BB2

So R4 and R5 have an ethernet connection between them and they are also
connected via frame-relay cloud through R1. IE uses delay to achieve the 4:1
ratio. Anyone who has worked this lab can shed some light? I thought I knew
unequal cost load balancing but I guess not :(

Thanks guys!
