Logging to the nearest minute or 5 minutes?
I'm in the process of hour building before I start my CPL. For my PPL, most of the instructors that I flew with always used to round the time to the nearest 5 minutes but some used to make me log it to the exact minute. As I want to make sure my log book is as kosher as possible when presenting it to the CAA, what is the acceptable format? Rounding to the nearest 5 minutes looks neat and tidy but also looks unrealistic. I'm assuming the CAA would prefer the more accurate time or is rounding perfectly acceptable to them?
Many thanks,
