You could aim for it, but you'd eventually miss. You couldn't hit the target by simply sizing your redo logs, since activity will vary - some days you get 50 GB, others 200. So your window would start creeping all over the 24 hour clock, left to its own devices. You'd have to institute a job to force a log switch in the slower hours I suppose... eh. Do-able I guess, but kinda messy - you're back to checkpointing at a time interval, not a data interval, which is not my cup of tea.
