It isn't my figure. But I did some back of the envelope number crunching for the last 12 months of NW's existence. If you take mainline traffic at DTW, MSP, MEM, MKE, and IND and without accounting for any hub-hub traffic (which likely overstates the "hub" traffic at MKE and IND), DTW clocks in at 40% of enplaned NW passengers and MSP comes in at 44%. I'm happy to have someone offer different calculations, but ~40% seems about right.
