WTF is goin on here?? All my gym numbers are about the same as yours including height/wt/squat/ratios, etc and my jumps are about 10in lower than yours!!! How is this possible? What's the secret ingredient?? 
Awesomeness.
Well then seems there's no reason to train at all based on these results. I'm takin the rest of the year off. See ya.
LOL!
@fedexpress : Ive been reading your journal , your jumps are indeed very low for your strength (absolute & relative ). I mean it's not like we are beasts or something , but having relative strength of ~1.75BW and reasonable bodyfat does not go together with your ~20'' jumping ability!
Few things i noticed:
- You are coming out from a serious detraining , 235lbs , 21%bf , some serious injury etc. Your body composition improved to a decent level now but it takes time to get back to a decent performing steady state , takes more time the older you are ( said the 37yo kid ! ).
- You haven't been practicing jumps much. If you're interested in jumping you must remember it is a skill that needs practice. You should jump ME 2 times a week and 1 or 2 more sessions of submax jumps ( or ME with low volume ) will not harm you.
- I didn't see much deep squatting. I love half squats myself , but always keep some deep ones in the plan. Your 1 leg parallel box squats demonstrates this too IMO. Our half squat numbers are the same but you are struggling with 45lbs on the SL , i can do 20 reps easy with that weight.
Still , if you just went out and jumped a bit more i'd expect you to reach 30'' rather soon and easy.
Looking forward to see your progress.
Vag, thanx for the analysis & advice. I think ur def on target abt the lack of jumping practice. My full squat initial goal was =>1.5xbw per Kellyb's advice and I reached that cple of months ago & then tore my calf which has set me back 4-5wks.
I switched to half-squats bcs I think it will give me more bang/buck and also causes much less meniscus pain. Still do the full ones during warmups just to maintain a certain base level at full rom. 1-leggers r fairly new so think more time will def improve those.
Overall, I was trying to take things 1 phase at a time, i.e. reach decent squat/bw ratio 1st, then start jumping more to express this greater strength. I am going to prioritize jumping wkts over the next month & will see what happens. I'm so far below the ColCoolJ calc estimates jumps that its a joke.
Also, in my early 40's was still able to barely graze standard 10' rim off 1-2 steps w/lower sq/bw ratio but was playing bball pretty much every day. So I'm pretty sure more jumping is the missing ingredient.
Lastly, and mb most importantly, I'm pretty much a training addict so i'm constantly overreaching/overtrained bcs I hate to take days off (feel like I could/should be doing more). Even just 1 more day's rest last week btw jump/squat wkts bumped my vj up 1-2in from the prev week's result.
Once again, thanks for ur help & wish u continued success towards ur goals.
