What I read is an unbalanced, vague impression. FWIW: it doesn't make me say: "No no no, this is completely wrong!" - but that's about it (BTW I'd leave the RM out, in this case. Just DB).

In order to be able to assess or even sensibly talk about such things, you need a better vocabulary. You snipped the stuff that might be relevant to that.

Here is a vague impression of mine.
I think this problem area is related
to an earlier conversation we had:

No.

Yes. So I'll repeat:
It is important to find a good way of stating requirements. Up to now I don't think you have found it.
