Errors is Dates leaving/entering the US in N-400

[tobias2801]

When I just reviewed my N-400, I discovered a few errors in the dates I put down for trips taken outside of the US since becoming a LPR.
On the application I used dates from a tax calendar I am required to keep for work where we track days outside of the US for potential tax implications.
Since I track full days outside of the US and not the days I actually left and entered the US, my information in the N-400 now does not match the stamps in my passport for a couple of trips.
Is that something to correct during the interview or should I submit a new page 4 of the N-400? The errors have no impact on my eligibility in terms of having spent too much time outside of the US - it is just that the dates don't match the stamps for all trips. Any advice?

I also have two trips where my passport was not stamped at all (the border officer scanned my green card and passport, asked me the typical questions, and then just stamped my customs form and waved me through). I can provide frequent flyer records showing that I took the trips. Does anybody have any experience with this?

Exit and entry dates don't count towards days outside US, so in your case it's not an issue.

For the two trips not stamped on passport, you must disclose them on n-400. Showing additional evidence of the trips is not a requirement, but some IOs may ask if you brought any evidence to prove the trips. If you have anything showing the travel dates bring it to interview, otherwise don't fixate on the issue and rack your brain over it.
