Off to bed any minute now, but just saw this and had to mention something at work before thread moves on in the morning: A while ago a couple of people left at the same time and interim managers were appointed in their place, one of whom is quite young, no experience etc., and what has absolutely stood out is the level of mentoring and guidance and help he's getting from the other male managers, in contrast to the woman who got appointed. It's not that they won't help her if she asks; it's just that they've never pro-actively offered help the way they do with him. At the planning stages of meetings etc., I heard them say things like "Dave* will need a bit of support here, so maybe I'll go to that one with him and I'll dig out the old contract so we can have a template" and of course, he just accepts that support as part of normal life and doesn't feel he's being given anything extra or has an advantage in any way.
Meanwhile, she only ever asks for help when she's really stuck, because she clearly doesn't feel she has the right to ask for it. And it's not that they won't help her, it's just not embedded into their thought processes and assumptions. And when they do help her, there's an attitude that has crept in that she's been in post long enough now to have picked it all up and she shouldn't need that extra support anymore, so of course she's inhibited from asking. No such attitude has crept in for him.
When the interim period comes to an end, I wonder who will be assessed as having done best? And the men will wonder why women don't perform as well as men, they try their best to promote them and it's not their fault they're not up to it...
So returning to what you were saying Buffy, I strongly suspect that the reason they can't give you consistent parameters, is because the parameters are different depending on who you are. 
*Dave's not his real name.
