I'm going to hit 75k on CO in less than a month after a PAINFUL half year at gold on AA and silver CO (came off a year where I made 100k on one airline, AA plat, and one round trip short of SWA A list only to not travel the following year). End of year will be just around 100K-110K EQMs on CO.
If I was not going to hit plat this year I was looking at $0.05cpm ai pretty easily (had two trips ready to pull the trigger). If you accept that you are not going to get upgraded as *G, it does open quite a bit of codeshare flights for the EQMs. Then again, it depends on how many miles you need I guess.
