One question, answered from the books
Why am I farming well but still losing?
Because farm is fuel, and you are not driving anywhere. A clean clear is the entry fee, not the win condition: the seconds it buys have to convert into something the map can feel, a Dragon taken on time, a deep ward, a gank that takes fifteen seconds, a cross-map trade. If your CS is high and your influence is invisible, you are in the classic shape of the Tempo Trap: motion without a named play. The other common leak hides in the same scoreboard, a level lead beats a kill lead, but only if you spend it while it exists. Farm that never gets spent is just an inventory.
The decision, as a picture
What it looks like in a real game
Two games, same 8.5 CS per minute. In one, every clear ends with a named play: ward, gank window, reset, pit. In the other, every clear ends with a hover and a shrug. The first player is called a macro god in the post-game lobby. The second one posts his op.gg on Reddit and asks why he is hardstuck. It is the same farm. It is not the same game.
The concept: The Tempo Trap, again
The Tempo Jungler exists for exactly this player, the one whose fundamentals are fine and whose time evaporates. The one-line audit: a fast clear that ends in hovering is motion, not tempo.
"Kills are temporary gold lead."
"But potential that never converts is just time spent."
