Got this book a couple weeks ago from the author while taking a class in Idaho. The drills are great but for me the best part is the training schedule and the included commentary.
I have struggled with poor dry-fire discipline for years mostly due to boredom. I would find myself doing the same few drills a few times then quitting because I did not really have any idea what to do next, with the included schedule and the breakdown of the drills into different training sets I can work on the areas of my game that need the most improvement.
The book lays out every area of the required skills to excel at USPSA shooting and breaks the dry-fire routines needed into small, manageable chapters. If you need to improve your marksmanship then follow the drills in that chapter. Need to improve your movement skills? There is a set of drills laid out for that.
It doesn't get any easier, all you have to do is put in the time to improve your action shooting skill set.
