Might have put wrong amount of weeks on activities lists?

Sorry I know everyone’s asking questions like this but I’m in that post-application frenzy and don’t have time to look for threads from people who have had the exact same problems as me

For two of my activities I estimated the amount of weeks per year since they were with the school and roughly once a week and that was the amount of weeks the coordinators said they put since no one really kept track. But now I’m thinking it might have been less… Basically the seniors sort of estimated because they were more casual groups. In one sometimes we’d meet for two hours other times we’d meet for 45 minutes and it was usually once a week but now I’m not so sure… Upon reflecting I think it might have been closer to 20 weeks but I just figured in total I had to of spent around 30 hours that year on each club so I just put that. The other I put two hours a week for 25 weeks because I figured I spent around 50 hours on that activity that year since it was a LitMag which I wrote and was an administrator for so I figured I spent maybe 20 of those hours writing and 30 administrating but who knows since no one was really sure or keeping track of hours so it might have been more?

These are casual groups so it’s not like anyone could verify anything right? Like how often do they really check on these things? Do you think estimating is really all that bad or am I panicking for no reason?
