Query: Review for 2011, fourth edition

I am a big fan of James O'Shaughnessy and I use a number of the strategies he outlined previously with good results.I have returned my copy of the 4th edition. The previous editions had updated data for each strategy discussed, plus new strategies that were examined. Unfortunately, this edition does not. While I am interested in hearing his new findings, I expected, wanted and needed data updates for all the strategies previously reviewed, particularly those I use or am considering using. I was totally surprised and disappointed by this change.I highly recommend his 3rd edition of this book.
