From the Chicago Tribune, a construction I am constantly trying to get my student writers to avoid:
"One independent publisher whose Amazon order was 75% lower as compared to last year told Publishers Weekly that they were facing a 'nightmare scenario.'”
75% lower THAN. There is absolutely no reason for "as compared to" unless you are getting paid by the word, and students writing theses and dissertations are not.
The above is a post from one of my friends on FB. Do you agree with her? I am a bit dubious.
