Accidental misrepresentation of hours in common app activities section

I am freaking out because of a mistake on my common application. In the process of re-working and editing my common app activities section, I accidentally recorded that I spent 1 hour per week for 36 weeks each year. This is a misrepresentation that I missed because while the activity does last for the duration of the school year (all 36 weeks), if I average out my hours it’s more like 18-20 hours rather than 36. Should I submit a correction?

No, immaterial
