Should I elaborate on an EC

I put 15 hours a week for 25 weeks for time for student council because I am up there every weekend all day for 4 months because my school hosts a large event that we host. I also have it as a class, but I feel like this sounds unrealistic. Should I elaborate on this in the additional information section to explain why I am up there so much?

We have no idea of your targets. Or what this event is, what its impact really is, beyond just your high school. Eg, planning for prom can take a lot of time, but isn’t an “it” for many colleges. And you need other activities for most colleges.
