As promised, here's the report I wrote for my PhD Stage 1 progression in the hope that it is useful or interesting to someone. I've made some very small modifications to the submitted copy in order to remove some personal information.
I'll reiterate something from when I published my proposal:
A document produced for one institution's expectations might not be directly applicable to another. … You don't have any idea whether it has been judged to be particularly good or bad one by those who received it (you can make your own judgements).
