I agree with this. I look at a few of my coworkers that only travel with me but not nearly as much or any on their own. I buy all the tickets so they can get E+ with me and know what we spent. Last year one had ~$2600 in spend with under 20K EQMs. The trips from Vegas were BWI, DEN, SMF x2 and ORF x2. He was well over 10 cpm.

The year prior the same guy had 6 Denver trips for around $3k and under 10K EQMs.
