I don’t think people have done the numbers, in part because he isn’t in “everything”, just overexposed.
The problem is that the schedule for release usually isn’t under the actor’s control and you can have several major projects with large marketing efforts one after another.
If you don’t like the actor and frequently watch media that includes movie or television promotion, that actor will be on constantly since they are promoting several major projects in a row.
If you start to bring up parallel universes, there may be a parallel universe where Petra Parker goes to shitty school.
The animated Spider-Man movies has Miles go through an internal crisis where he tries to flunk out of one of these schools. Maybe Petra does the same or maybe chooses/doesn’t take the test to get in.
You can also have an alternate world where Petra gets excluded for some reason. Maybe the NYC bankruptcy goes worse and these schools vanish or a mayor puts a fee to them which Petra can’t pay for.
