Do you have any reason to disagree with the final sentence:
"Andreas has claimed that the text that is identical in his Phd to uncited sources is just composed of “common phrases”, this is highly unlikely to be the case since the indentical text is usually more than 9 consecutive words and is only found in one other earlier source from which there are usually multiple 9+ consecutive-word identical phrases in his Phd."
Do you have evidence that it's actually "relatively common" that sentences with many, many more than 9 words are identical?
