I'm working on one. I'm testing all the way though, so I'm verifying with tests the statements I make. I do not want to just parrot the manual or some post or my own observation, but have tested and proven in the game engine the plan I propose. Testing that much takes time. My document has already changed several times due to things I've learned in testing or through the questions or points raised in this thread. And I am fleshing out concepts along the way. It's getting to be a pretty long document. I've been thinking of writing it in 4 sections:ORIGINAL: Revthought

Not much of a wall at 50 shown in this screenshot.
It is my understanding (and experience) that the 'wall at 50' is WRT experience not individual skill sets. These in my experience can train up to 70 quite easily. Experience much over 50 requires some sort of mission other than training.
What kind of experience are we talking about? Overall experience or skill experience? I find that you can absolutely increase skill experience past 50 with training. In fact, I usually don't (I am not saying what I do is the most efficient) start running pilots in actual "combat" missions until I've achieved at least 60 in all of the relevant pilot skills for the type of aircraft they're flying.
Edit
While I am a data scientists by profession, if not training, what I really don't want to do for the games I play is test these things myself; therefore, what I need, and players like me need, is for someone to tell me the absolute best training regimen so I can implement it into my play without thinking too much about it. [:D]
1) a plan to follow (checklist)
2) tutorial for the checklist (how to look at each squadron and what to do with the squadron to optimize if for training case studies)
3) principles behind the checklist
4) test results supporting principles in the checklist
The idea would be that someone could just follow 1) & 2) without a lot of effort, but could read it all if they want to spend the time and understand the why rather than just the what. It will be from the Japanese perspective, but most principles should carry over.
