Yes , i still can't get why you're not jumping way higher. 320@169, WTF , that should have you in the 35 area.
You're very strong relatively and absolutely , lean , you do your plyos , you jump often , don't get it! 
Then again you had many derails, those are major bitches.
High-freq jumping sounds nice , be sure not to wear yourself out though. When i was jumping almost every day last year , i would label most of those sessions as 'submax'. Psychology trick , just like you described about gym session : no expectations , no disappointments , just adaptation and technique improvements. So i would go like , e.g. , Monday submax , Wed submax , Saturday caff-up + ME. Worked nice.
Just saying... 
yeah this is pretty much what i was thinking. jump more, care just enough to try to do it properly but not enough to get down on myself when i'm not jumping well, keep getting stronger. in other words, back on the arowe plan but with more or less DLRVJ depending on how i'm feeling that day.
also, i wouldn't say i'm very strong either relatively or absolutely. especially compared to some of the other dudes on here. but all that means is there's nowhere to go but up.
