It is X with a given attribute of "good," not all X; thinking it is all members of X is what you are missing here. Most good PMs would review tickets, by definition. That bad ones do not is irrelevant to the argument, so it doesn't matter how many someone elses notice their PMs are bad, like yeah, no shit.

Anyway this is delving into pedantry deriving from the fact that you seem to have missed what I had said above, rather than engaging with what is going on with regards to PM productivity itself. Have a good day.
