I was recently adding up my time and noticed that somewhere during my private training I think I screwed up the addition and am off by about 10 hours (meaning I might have around ten hours less than I previously thought). Whats the best way to go about correcting this? I am almost all the way through that logbook with around 1100 hours now and dont want to cross out pages and pages of totals (some are in ink and some in pencil, from the days before I realized that pencil totals are SO MUCH easier in case of a mistake) because it will look awful for my next interview. Is it better to just transcribe into a new logbook and add the hours up correctly and but keep my old one with all the endorsements in it in case someone needs to see them? Or does ten hours really not make that much of a difference in the grand scheme of things?

I have to go back through my logbook to see what the error really is, but I thought I would get some opinions from anyone who maybe had had a similar problem. I also have had some instructors early in my training log stuff in the wrong column that I have since drawn a line through like logging flight simulator time when it was only an FTD. I guess those issues probably happen a lot in student's logbooks from instructors who don't know any better.

What do you guys think about the flight time issue?
