The MD90 just doesn't have enough wing for those kind of shenanigans
Been on the ER for a bit now and haven't seen it there...so I'm happier just saying it's a Mad Dog thing
Having said that, I've also never seen the ER just blow off an altitude capture...so there is that...
Oooh I've seen the ER blow off altitude restrictions on descents plenty. Some planes it seems like it gets within 400-500 feet and goes "welp, that's good enough for the girls I go out with!"
As far as the going to idle at TOD without descending while in VNAV PATH, I believe that is specific to a couple of arrivals out west. I've seen it for sure going into SEA and I think there was a memo about it. Something to do with how the restrictions on the arrival were coded into the FMS. But I think it's an anomaly that only occurs if certain stars align.
