First post here. Just wanted to add that I had a lot of success with this plan the first time I ran it, particularly in the squat. It will lock your technique in and, given enough calories, build a ton of mass in the legs and back. Went from 425-430 to 468 in a meet. Ran it again a second time but did not see the same success. Bench and deadlift can be hit or miss, most of the people who claim success get the gains mostly in the squat. My bench did go up though, from around 300 to 314 on the platform.
I recommend running it once exactly as written, then if you want to play around with volume and percentages I'd say go ahead.
