just a thought, maybe he had a fluke moment..I had some insane jumps when i am super relaxed, like 5-10inches more than normal jump due to being unnaturally calm for no cause
5-10 inches??? 
I've had that with ~2-3 inches but a 10 inch increase out of the blue from being relaxed.
I'm not attcking you BMully, everyone is different and i just felt like posting the pic 
i don't lie, i got super relaxed in a game and almost dunked with 2 hands, head was heigh as hell, this was 8th grade
Yes yes. And I won Mr Olympia. It was just a fluke. Im back to fat now again.
that is a physical change, not possible to do just like that..in times of extreme pressure or extreme relaxation, people can get super human abilities..that is how i grabbed rim as 13year old who could only normally get half way up, this one jump i got rim, then it took a while before i got it legit everytime...the cns is responsible for strength and power, we develope it to allow more, but it is always capable of that power
ya bmully is definitely right about a substantial performance increase, verkhoshansky referred to it as the 'innate (protected) reserves'.. in which access to that strength/force output is restricted, but through years of proper/aggressive training, athletes can keep improving how much they can tap into it at their own will.. i mean, i remember i was jumping shitty say 5 months ago, then that cop pulls me over, and i jumped like 3" higher after alot of fatigue, that wasn't even life or death, but that small adrenaline response/heightened cns arousal lead to some gains..
level-7 = PR city.
True. But claiming a 10" sudden increase is idiotic. Thats like when Rip claimed that crazy crazy sprint time because he saw a spider or something like that. Actually I dont remember if it was Rip, but someone did claim to run a crazy time, faster than world record speed.
btw yes, that was rip that ran a WR after having a spider on him 
Hehe. I thought I remembered it. 
Yes, athletic improvement can increase during certain circumstances we all know (Lev 7 MANG). Yes 10 inch vert increase suddenly is about as likely a sudden 100lbs improvement in the bench. And yes this is a long quote, quote, quote, quote, quote. And we all know that rip pr'd becuase that spider was a super duper mega jumping spider, and when in landed on rip, some of the exlposive and elastic qualities of its legs were temporarily fused with rip's Bi-legged frame.
