Match FPS, GOP and samplerate

I'm having a question about this article:

In the segment Exact durations it's recommended to choose the GOP-length so that video and audio match exactly.
In the following a formula is shown which confirmes the match by delivering the AAC-Frames.

My question now is which AAC-Frames-Values indicate a match? Is the criteria that they are integer? But that would mean much more options than listed in the tables of the article.

Thanks for your help

Re: Match FPS, GOP and samplerate

I'm asking this because I've heard if you shoot 30 fps or 23 fps you will have a problem with the audio
Let's say you record on double system on a DSLR and you have an external recorder. the audio will have a lag, is this true?
