If I were you, I'd keep your hard earned $84 in your pocket. Their website copy reads like any mailing you'd get from Empire Press or any other system seller. It's mid July 2009 and the example they post is from January 2008. No free selections given before the reace is run to check out the method.
When you click on "buy our book", the copy is pretty poorly written, grammatically and otherwise. Claiming to hit 70%-100% of races played is a little too much, but I'll bold my favorite quote:
In 11 of our chapters we handicap--so you can follow-- eleven 2008 races
*with notations in color for ease of understanding
*with past performance and results charts from the DRF
showing you EXACTLY how we win at various kinds of race,
from Stakes to races for horses 7 (seven!) years old and older!
Sspecializing in races for older horses is one thing, but 7 years + is pushing it.
