This is one of those things that you will never know. I am telling you right now up front. If it's going to keep bothering you, go to a dealership and have them scan the logs. But that might backfire as well, if you did do a minor overrev, its still an overrev for them.
My concern stems almost entirely from the issue of whether or not the tach is accurate as to actual engine speed. I recall a thread stating, on acceleration to redline in any gear, the tach "lags" behind the engine's actual revs. Although I did not enter red, and I am 99% sure, if there is a lag in the readings than I still could be screwed, no?
