Those were just numerals pulled from thin air. You can totally pick better numbers.
-What follows is just my opinion-
If you’re using the rep-max calculator, I would keep the projected max pretty close to the same for weeks 1-4.
If 225 x10 = projected 300 max
Then your (week 2 weight) x 4 should project a max around 300 too.
Use the 4 productive workouts to drive your max up over the course of a month. Don’t try to increase your 1 Rep Max a whole lot, every week, for months.
How much weight to add month to month depends on how long you’ve been training. 10 pounds, maybe 15 tops, if you’re a young stud and you picked lighter numbers the first time. Less, if you’re more experienced. I heard Ed Coan say he’d run a 12 week plan to get 10 pounds on his lifts.
