It's so difficult to say. Hopefully there will be some kind of dialogue and if more needs doing they will let you know? It does sound like you've done a lot.
I got minor corrections, which they said were substantial, but it only took a week max for me to do, so to me they are small, basic things. I think they overestimate the time needed, which makes you think you need to do more than you need to do. Having said that, I am waiting for the internal to sign off my corrections, so who knows, maybe he will say they are not enough!
