Hey, plyometrics training?! thats good to see. Jumping training is one of my favorite workout regiments.

I'd do quite a more advanced cycle then the one you proposed. I definitely think you should alter it. I have no clue why squats are never included in your weekly workout. They're the corner stone of plyometrics. Remember: you're trying to make your legs as explosive and powerful as possible, so your exercises should mimic the jumping motion.

Regarding your question on jumping during the day, it's not necessary. You want to give your legs time to recover. Jump training, if done properly will make your muscles burn like no other. Rest during the day and save the jumping for the gym (do box-jumps 5 sets x 25) increasing the height of the box after each set. (if possible @ your gym)

Good luck. I made huge gains from jump training in the past and my vert is still 40". If you work hard at these I bet you will gain those 10" within 4 - 6 months.
