Ok since you believe it all answerer this:
1. Which organisation/company does the person making the analysis work for?
2. Did that organisation/company order the analysis?
3. What is that organisation/company’s interest in this?
4. What are the credentials of the person making the analysis?
5. What other analysis of the physical site did that person make if any?
6. What additional analysis/tests, were used to come to these conclusions?
Not be picky but these are fundaments questions you should ask before jumping in and making statements.
I believe there are some technical errors in the analysis presented.
It does not take a complete idiot to see them either. (That assumes you are prepared to actually look before making judgement)
This may not alter the outcome but since these errors exist that leaves questions.
