Hey guys. Im looking to increase my vertical (currently 62cm, want to hit at least 80cm in 6 months)

I was looking on the internet for a system and I found one, its in my signature. the website is http://www.increaseyourverticalhq.com, i have been doing it for 2 weeks. the first week i saw a gain of 5cm's but now im plateau'ing... i got 0cm in the 2nd week.

does anyone with some experience know how long this kindof thing takes? whats the best way of doing it? the book gave me a system involving squats, dl's and plyo's. i picked the one that was suited to my strength level (it has a bunch)

do i eat for mass or strength?
