I'd really like to take some time someday and dig around to see how well the NBM fares compared to MAV/MET. Tomorrow night could be a real fun example to look at. Tomorrow night all about radiation I suppose. Here are some differences
MAV, MET, NBM
BTV: 31/32/35
BDL: 36/32/36
BOS: 41/42/43
EWR: 42/43/47
CON: 27/26/32
TAN: 29/30/36
