Hi, I've honestly read the FAQs and the website but I still have a few questions, I may be just be reading too much into it but here it goes. I'll break it down to parts to make answering easier 
1. Should the weight be heavy enough so I can ONLY do 2sets of 15,10,5s?
2. So let's say my max reps for 15s are 100; 10s are 200. I
increase accordingly for 15s then on my 10s 2week cycle, do I start increasing from 200? or should I just keep increasing from my 15sets 2week cycle.
3. Should I use this sample workout for my HST program? http://www.hypertrophy-specific.com/hst_notes.html
(probably yea
)
4. I've read that you increase 5lbs. for upper body and 20lbs. for lower, true? because I see in the sample 2 week cycle using 10 reps, the leg curls are going up by 5s
http://www.hypertrophy-specific.com/hst_notes.html
5. The leg press in the above sample workout, seems to be going up in irregular numbers, what should be the exact weight? 20lbs?
6. So you assign your max weight to the final workout of each 2 week block and then decrease in 5-10lb. increments. What I see is that even on the days you aren't doing the workout, you are still decreasing the weight (like squats, leg press, squats) is this an error on the website?
7. After I'm done with SD, do I start the whole cycle over with the max weights of my past 15s, 10s, and 5s and start increasing from there?
Again, I apologize if this has been clearly stated but I have really done researching and these questions I have a lot of trouble getting answers to.
I have been working out for 5years, started with starting strength and then moved onto to 5x5 mad cow and now I'm looking for a new workout since I haven't been gaining.
Thank you for your time and effort. I know it's like drinking from a fire hydrant
