It is only a warning, but it means there is potentially an issue in your page (N+1 requests because of proxy initialization in a loop for instance). The warning is here for a reason. Such number of queries is often an issue

Yes. Are you saying here we should tell the user more aggressively that they should keep the number of queries below 50?

well, they should be careful if it goes higher (especially if it happens often). Note that 50 is quite arbitrary here. Blackfire may turn the corresponding metric into red on a different threshold for instance.
the general rule is that lots of DB queries is a bad sign for perf (because DB queries take time)

I like the clarifiation, but I think it's a bit too long. What do you think about:
The icon will turn yellow if there were more than 50 queries on the page, this could indicate that something is not correct.

Sure, sounds great to me. I was mainly concerned with getting the information about the yellow icon in there.
