The recommendation is to contact your MP after 11 months in London. Your application has not been in London for 11 months, so I'd wait. YOu know things are progressing because you have your notes, and there are tons of others before you who still haven't heard. You've ordered notes again so you'll get an update when you see those.
CIC has at least acknowledged your medicals. They will either ask you to go have new ones done, or they will choose to extend them. I've also seen some cases where they are jsut about ready to issue COPR, so they'll just extend medicals for 2 months so that you have time to land without having to get new ones done.
So my suggestion is to wait to see what they say about your medicals, and wait to see what your notes say. YOu are still within processing time, and if you've lived in other countries that tends to take longer since there are more checks required, as your notes have pointed out.
Wait utnil your application hits 11 months IN LONDON before you contact your MP.
