Were you somewhat fit/active prior to 2011? Because to have an 29" SVJ at march 2011, is quite incredible, and i'm guessing that prior to 2011 you had some decent strength.
It's not that incredible I think. Athletically I've always been "above average", not elite but competitive, and also played ball a lot around 15-16y.o....I think you'd find most people in that category would have acceptable SVJs without much specific training for it.
Not incredible but not half bad either. At Vert gym I was able to test some graduating high school kids; they were decent track athletes (the best were low 11 100m, ~38 300m hurdles), football players, but none were extensively weight trained. What was surprising was how divided the jumping was by height. None of the taller kids (6''2 + ) jumped higher than 26 inches, none of the kids over 6 feet went over 28, and a couple of the shorter guys got into the low 30's. RVJ they all went much higher and the division on height was much less. Anyhow, a fit athletic kid jumping 30 inches suggests pretty good potential.
Thanks man, interesting observations. I'd love to see a study on femur/tibia lengths, height and SVJ in trained individuals and see if there's any correlation.

Gym - Strength block week 1 (yesterday):Full warmup, foam roll, mobility, glute/VMO activation
Squat: warmup, 2x6@60kgs, 2x6@100kgs --> starting nice and easy, will obviously ramp this up. Was sitting back on my heels a lot better today.
SL TKEs: 2x20/leg@15, 2x20/leg@20kgs
UB: Bicep, BW dips (3x8)
My rough plan for this block was 2x/week squatting (1x6 and maybe a 4x8 depending on how my body handles that volume) + calves, 1x/week RDL+assistance+core and 1x/week 30min core session. I might hold off the RDL for this week because I'm a little worried about this minor twinge in my glute, could be piriformis/sciatica nerve pain coming on. It feels normal today after squatting yesterday, will see how it holds up. I cannot be bothered dealing with another thing right when I'm trying to build my strength up again.
