The important (and crucial) aspect is the gradual decline from that number on down. If we used that logic, you could argue that one could skip forward to the 40 day mark (nearly 6 weeks post final injection) and just start a gradual taper when there's only 62.5mg of Test E in the system. Well, you would have to agree that this notion is foolish, because the entire concept of the Taper protocol is a gradual and even decrease in Test levels, not the downward spike of it.
The most important weeks will be those that hover right at the levels of natural production by the gonads, which if we suppose the "average" figure is 7mg/day then that is the ~50mg/week mark.
The gradual mark at 100mg/wk is a good idea because it will allow the receptors to regulate, it is not just a formality in time and order. This will help replenish and reboot that GnRH, LH and natural Test as well, and thus re-sensitize them in a way and if I recall correctly Prisoner stated it would help the binding globulin to drop. I would imagine if you went that 30 day period without the least bit of a taper you would find that a great deal of that alleged 1000mg left in the bloodstream would aromatize drastically, leading to libido and mood issues.
You're straying from the concept of the taper itself by going with the old line of thinking that the "taper" comes natural from the ester's half-life. Basically, it's a bastardization of both.
