As you can see from my timelines, they aren't consistent about processing times. Nobody knows how they work there. Even i wasn't expecting anything before 1st week of July because current processing time is around 24 days. I wish you hear from CIC with good news soon.
MyCIC is the best source of seeing updates on your application. In our case as well, medical was updated after a day or two. other than that they usually update the final decision after processing application. there are other details also, like interview, documents review, etc. but i never saw those stages get updated. they simply remove all these stages (rows) when they update final decision.
Hope this gives you an idea.
GoodLuck with your application!!
