From what I have heard, they are mainly looking to see that your day plus your night equals your total, your single-engine plus your multi-engine equals your total, that you actually do meet the minimums (and you met them when you applied and didn't "fudge it" to get your app in sooner) and that there are no questionable entries or times that are out of proportion (like your actual instrument being half your total time). Other than that, I wouldn't get too worked up about the other things. We all have some crappy hand-writing and blue ink in our logbooks. If you can, go back through your logbook and find the error. Its a pain in the ass but it will work out better for you in the long run. Just draw a line through the wrong entry and write the correct one above or near it. I have heard that some airlines and the FAA do not like to see a lot of white-out or green-out. How do they know you didn't white out the time your instructor wrote in there for a multi-engine flight and double it?
