Doesn't help since I know neither your establishment, nor your department, nor what it does, nor how good it feels.
Well I'm not going to reveal those kinds of details, as you would imagine that would potentially de-anonymise me. So you'll just have to accept what I tell you to be true - or not as you wish. It is true, by the way.
So 99% of our research was either 'internationally excellent' (termed 3* in REF) or 'world leading' (the top level 4* in REF). Overall our department was ranked 7th in the UK (out of 89 universities that submitted to our area of research). In terms of research publications (arguably the most important aspect of academic research) we were 2nd, behind only Imperial.
You can choose to believe this, or not, but it would be really weird to just make this up if it weren't true.
