It's pretty simple. Weight starts low(65%), reps are high (8-10). By end weight is high intensity(90-100%), reps are low (1-3). For Oly's 5>1 reps, Intensity increases. I'm not sure about the power-speed phase. I don't have much experience, but this type of periodization seems sort of lame.
There are different schools of thought on maintenance. Some say just try to maintain hypertrophy, so do like a 2 day split with 8-10 reps on everything except oly's. Some say do do a really low volume and maintain high intensity.
