I'd just like to chime in with two things.
Firstly, nice graphs. That really lays out things in a simple manner, both for anyone reading this thread, and more importantly, for you.
Secondly, you're likely stalling because you're following an inherently scattershot program that won't ever let you get good at any one thing. (Sorry, but it's true.) Get some goals (the S.M.A.R.T. kind, not "improve functional fitness"), then do workouts that seem reasonably well suited to helping you reach those goals. Six weeks later, evaluate and see how well suited those workouts really were. Tweak as necessary then rinse and repeat.
And yes, I'm actually holding that handstand. Get on my level.
