I think a lot of people just are not using the search options correctly. If you posted something more than a year ago, its going to be way quicker to sue the search vs scrolling through all your posts. As for 24 hours vs 48 vs something else, my logic was than if you wanted that just set it to all as I suggested for you. That way you can scroll back however far you want, 1 day 10 days, a million days as the posts are listed cronologically.
