"Being able to casually roam around freely across linear time qualifies for immeasurable speed. However, traveling to different time periods through movement is a common feat in fiction that often leads to inconsistencies and has been done via FTL travel or running laps around the earth faster than it rotates. This can lead to characters being assigned an additional, independent, speed rating for the ability. This should preferably be evaluated case by case."
They have this note, because multiples series moving faster than light is enough to travel through time (Fire Force, The Powerpuff Girls, one of the Supermans, etc), Turma da Mônica isn't one of this series, the series literally show that moving faster than light don't make you travel in time.
So Turma da Mônica can get Immesurable speed (Or Time travel via running If don't fit the requirments to get Immesurable)
