DC Routine: does it really work?

[Dirty Workout]

This is a fantastic program. In 4 weeks, I have made improvements in strength, size and weight

There is too much positive feedback from those who are doing DC for me NOT to try it

thanks for the input so far. i think i'll give it a try. but i got a quick question:
dc stated that, when you begin, you should start out with straight sets. so does that mean, that each of my one working sets is a "normal" set in the 11-15 rep range?
if yes, could i also do straight sets in the 6-8 rep range? i know that 6-8 works better for me than 12-15. or wouldn't this work in this training system?
