You will need to explain what your issue is. What is your level of academic expertise (you are challenging an MIT professor on math / data analysis).

I am a retired scientist who worked at a major university and I watched the whole video. It is well done. I did not see any significant problem. It shows signatures of an algorithm for vote transferring at play here. It's similar to the Benfords law analysis, though different. This allows us to identify the states, districts, and precincts where investigations need to occur first. It also identifies the candidates that benefited from the likely fraud.
