Keep in mind that all your previous improvement was due to the fact that you grew up. As you work your ass off for further sick azz gains in vertical jump performance, the collected wisdom of the Starting Strength community is that your vertical jump performance will increase no more than 8-10%. In case you're math skills did not grow up alongside your physical growing up (which is what caused your VJ improvement in case you still aren't getting that), that would calculate out to a post-growing-up standing vertical jump of between 34.56 and 35.20 inches. Be prepared, however, for the possibility that growing up caused all of the vertical jump improvement you'll ever see and 32" is actually your max. Which you developed by growing up.
