Requesting comps can be useful when short-term travel plans fit right. Example: When I knew I had to make several trips to a USAir hub in the coming months, I requested and got a comp showing my status with CO. However, my willingness to fly USAir because of comped status caused me to fly CO less. As a result, I was downgraded the following year from CO Gold to CO Silver. (I suppose I could have flown through a CO hub, but missing connections was too risky for my business needs.)
