Never let the truth get in the way of a good yarn.
MK-BN, 57 min. in a 717, 65 min. in a 146, in nil wind. ( even if you used 350KTAS for the 146 and 500 for the 717, the difference is still only 23 minutes )
From memory, wind effects all A/C the same on a given route at a given altitude.
350KIAS, not below 10000' these days I'm afraid, so thats approx. 30 miles when inbound.
Having travelled in both A/C, I would choose the 146, in case I got stuck in the rear of the 71 without earplugs.
Still, this thread is like most of PPRUNE, good for a laugh.
