Hey Sonny, I hadn't thought that Nitwit might have meant that his whole cycle was 2 weeks. Think he was referring to a micro-cycle, like the 2 weeks of 15s or the 2 weeks of 10s etc. That way his whole cycle would be 8 weeks (2 weeks 15s, 2 weeks 10s, 2 weeks 5s and 2 weeks post 5s, then re-test maxes and finally SD)
Not sure why you've said 3 weeks of 15s and 1 week of 5s though? Also, 9 days for SD is plenty when you start out unless you are a seasoned trainer. In which case 9 - 14 days may be necessary as you say.
Nitwit: As Sonny says, the FAQ is full of good advice so do give it a read.
