Midway, Midway, Midway, you are a most difficult patient. You aren't progressing, you are beginning to stagnate already(!) and it's obvious why.
You essentially do two things in parallel (at a glance):-
Your learning methodology is that of a juvenile Crow, who is elated to watch the adult extract a grub with a stick, but you don't yet understand how or why it works so you try over and over through unwavering repetition thinking you just need to try harder. You are gathering leaves off a tree with the concept of building your own tree but missing the core essential features all the time.
Then there's your, well I hesitate to call it ego, but it's something like that, competitiveness or insecurity are better words perhaps? You seek out 'better' pilots so you can defeat them once or twice regardless of circumstance and then immediately dismiss them. You'd even do this with Bruv if you could out match him. This approach is unique to you, since you do not factor in the amount of times they have defeated you before or since. No one else does this here, only you. You're like a British army soldier who throws a cocked STEN gun through a window to clear a room and then turns to his mate and says: 'nice shot eh?'.
As part 1 increasingly returns diminishing results, you do part 2 more and more intensely (as your recent BBS activity implies). It's as if you constantly have to give evidence internally and externally to assert to yourself that you are 'good'.
This obstructs your development even if you do these two things slightly and now you seem to do these things a lot! You've split yourself in two and are fighting on two fronts. Unwise.
Sorry if these comments hurt you but I know how important this game is to you and you are now on a path which, with every step, takes you farther from your destination.
