Synch Issue with Frame Rate Variation

I previously posted a thread (quite sometime ago), asking for help with decimation of duplicate frames in a video that had no decimation pattern. I thought it unnecessary to bump the thread since it is quite old. But, after many suggestions, I decided to go through the video frame-by-frame and manually decimate every duplicate frame in an overrides file. I achieved this, and the video came out quite smooth. The only problem is that the audio is not synched with certain sections of the video. I am thinking this is due to the fact that some sections of the video are 26 fps, 24 fps, and other variants. Am I right? If so, or if not, could someone try to help me with this? I have spent a long time trying to figure this out, but haven't yet. You might wonder why I'd spend so much time on just one music video, but I guess I'm a perfectionist . I would really appreciate it if someone could help me. I will provide the video and the scripts I am using on it.

NOTE: The reason that the cycle is set to 1393 is because I've only de-interlaced and decimated frames up to frame 1393.
