User997 said:What about my situation though where I typically won't fill out my logbook for months at a time (I keep track of my flight times on an Excel sheet). Then typically i'll sit down one afternoon and fill out months of flight times and trips in one sitting. I've always wondered if this will look suspicious to someone or if it was no big deal.
I do the opposite. I fill out my logbook within a couple of days of a flight, if not that day. I keep a backup Excel spreadsheet that I update once or twice a month.
