Raptor can vouch for that. Let me tell you the story: It was Sunday, and my legs were very tired (DOMS) because of BSS, whenever I do BSS the soreness in my legs is huge and it stays like that for up to 5 days. It's a killer exercise for me... but enough about that, I went in "student park" with nightfly and raptor, nightfly jumped over the car and sheet, and i felt pretty tired but i did something like this
http://www.youtube.com/watch?v=ps1QROaii10. Anyway after some kind of dunk session I was more tired than before. But i went in "titan" park and just stayed there, after an hour of loitering, i started slowly making some layups and shot at a 9'9'' rim. Than I asked raptor for the no. 5 basketball and started dunking off 2 feet ( i'm jump considerably more off 1 foot but i was too tired to do that) raptor immediately noticed that i'm plating my legs different, even though i was still going slow and lazy towards the basket part because i was tired and part because that's how i roll. Than i got warmed up, i couldn't feel soreness anymore and i started going almost full speed and plating LR and dunking, i was jumping about 10 cm (4 inches) more than usual. There's an "anger" factor, as raptor calls it that I was using for the first time in my life. I can't use it as well of 1 foot because i can't slow myself down to jump and i run into the fence or some shit like that. Maybe once in my life I had dunked a regular size ball off 2 feet at a 10 foot rim. that happend 4-5 months ago, after that whenever I tried i couldn't not even with the small ball. After my short session on the lower rim in which i threw some tomahawks, 180, 360, all off 2 feet, i went to the 10 foot rim and could dunk easy because i was using that "anger" factor just going full speed and really planting my legs into the ground like i wanted to stomp something, i could dunk easily off 2 feet at a regular size rim. Next day I dunked off 2 feet with 2 hand with a regular size ball on a regular size rim, I wanted to do that from the first day since i started playing basketball, and i thought i was so far from achieving that, but i realized that my calm attitude in general hurt me when i was dunking, 2 legged jumpers you need do be angry, go max speed and plant hard, that shown amazing results for me. I don't know if this helps anyone, I surely hope it does. I just wanted to share with the forum
