I'm considering a 0h36 connection at EWR, with a YX E75 inbound and a YX E70 outbound (DCA :: UA3467 EWR UA3531 :: MSP). I am aware this is a borderline insane connection, but I am wondering

(a) what are my odds of making this connection (in percent, not "you're nuts")
(b) what are my odds of at least having a C-C transfer? I'm pretty sure 36 minutes from C to A is flatly impossible, and also violates MCT.
(c) what are experiences with getting OALed in IRROPS? There's a 10pm nonstop on AA that maybe I should just be paying for to start with...

I swear UA once had a 10pm IAD-MSP...
