Thanks TonyW and IBflying for the info,
Tony you're correct, I was assuming cruise. My crj2 #'s are from a b737 (now) pilot that flew the 200 for approx 5k hrs. 3,000 pounds total cruise at .74 Mach is a good number and your .12 calc for statue miles matches the .146 for pounds per passenger per nm.
I also assumed the 12,000 pph for the MD-11 at .81 Mach, numbers per nm.
The Q400 70 pax would be .088 and for 78 pax is .079 in nm terms, not bad.
Again, the C-152 is an abysmal .16 pounds per passenger per nm....
