By "longer cycles", don't you really mean, "more gradual progression"?
Regarding the logic, I've got an idea to drop dealing with percentages and work more with increments. It goes like this.
First, actual lifetime 1RM in a comp is 320. However, we all know that a peaked comp 1RM is unrealistic, so...
Second, Just pick a weight I know I can do as a triple based on experience since the comp. I've done 5 @ 280, so 275 is an easy triple.
Third, I'm trying to build a foundation, and to stop choking and having form collapse when I make big jumps to top set, so the answer will be ramped sets with increments that make for a more continuous experience from the first to the last.
Fourth, an increment of 30 is a know-thyself answer for Ken to get that continuous experience.
Finally, there has to be a way to improve, so I just cooked up the 5# increments based on a program my trainer gave me before the meet.
As for burning gas, this is a deliberate decision to do so. It is a trade-off to obtain that continuity as the weight increases. I say to myself, "perfect form at 185 was easy, 215 is doable so do it." Then I'm saying, "You did good form at 215, 245 is doable so do it." The gradual increases allow me to maintain a steady frame of mind as I approach higher intensity.
Then I throw in a single afterward for the fun of it. Once I hit the backoffs fatigue is becoming a significant issue so it becomes all about maintaining focus and defying the fatigue.
Hope that answers the question. Nobody ever accused me of being brief.
