I haven't messed around much with high-end SB content because health issues making it hard to sit upright for long periods. But I can still recall doing many a Zurvan farming party that played out more like learning parties. Like, no bonus and right off the bat a BLM dies because they didn't move off the first falling platform.

Parser shaming was pretty common in learning parties too I can recall. I think it's okay for people to post numbers if the rest of the party okay's it before starting. But like, if you sign up for a first stage greenest of the green learning group that's still just getting a grasp on mechanics maybe don't post everyone's numbers without warning out of spite.
