you should read through some of his journal:

also, when you say 3,2,1 RM do you mean you plan on hitting an existing 3RM or set a new 3RM PR?
because, lets say you want to hit new PRs for 3,2,1 RMs ok?
so..
Exercise: Deadlifts
Week 1 = 405 lbs x 3 reps (3RM PR)
Week 2 = 410 lbs x 2 reps (2RM PR)
Week 3 = 425 lbs x 1 rep (1RM PR)
do you think those are PRs? nope. they arent. only week 1 was a PR. if you do 405x3, then 410x2 is a given. that is NOT a PR. in powerlifting the goal is to increase maximal strength.
therefore, it would be much more beneficial for you if you did something like this...
Week 1 = Heavy. Work upto something close to your 3-5RM
Week 2 = Medium. Do more quality volume with something larger than 90% of your 1RM
Week 3 = Hit a new PR
Week 4 = deload
then restart..
of course, all this depends on your training experience, strength levels, etc etc...but its good to give this some thought.
