The following is from News Week's 1997 edition. The time sequence seems quite confusing to me. Is this a normal way of wording of events in this tense sequence or is it peculiar to Journalistic Style? How could we explain the sentence in other words?

"When 3M recently reported that it invests more than $100 million a year in environmentally related research and development, the real news was that from 1973 to 1995, its 4.400 Pollution Prevention Pays (3P) projects have saved the company close to $1billion."

«I was implying that the editors of Newsweek may have looked this over somewhat hastily and missed the mistake.»

Thanks for the clarification, Jim.
