Texas method phase II deload
I'm a 31 year old male, 6 foot, 215 lbs, running the Texas method for the first time. It's brutal but a lot of fun.
My question is regarding how the deadlift deload works. I'm nearing the end of Phase I, and will finish Phase I deadlifting 430X5. The book says to deload 5% at the beginning of Phase II, and then continue with sets of fives with deadlifts until halfway through Phase II. I'm planning on running Phase II for 12 weeks, so this would be six weeks of sets of 5. So naively these six weeks would look like 410,415,420,425,430,435, only leading to one PR in six weeks. Then I would finish off Phase II pulling 465 for a single, which is 20 lbs below my current estimated 1RM. This progress seems too slow for an intermediate program, so maybe I'm misinterpreting something.
One option I was considering was to deload for just two weeks, so doing 415, 425, 435,440,445,450 instead. Am I being too greedy here?
