I disregard any activity with fewer than 50 hours. So, if it came to my desk, the good news is that I wouldn't care. The bad news is that you "wasted" a W/A spot. Telling me that you miscategorized this would not help you (to me).
Once you've submitted, there's very little you can do. For your well-being, don't go back to read and look for mistakes you've made. You'll end up worrying about it even more then.
