The mindset that sees an outline of potential results as merely a portrayal of a perfect win rate misses the point entirely.
A "net gain" takes in account for losing trades.
... and you wonder why some never make it.

If you aim at nothing, the never miss.

If you aim at a goal and move towards it continually you are progressing.
A structures plan of moving forward and constant calibration of your bearings... never deviating from the task.
This is where 99% fail.
Staying on task and not losing sight of the goal.

Most would be ground down by the slow start for the first few months... and try to overleverage or overtrade.
Blowing it before they see the fruits of following a model and risk plan.
You have been taught money management & proper risk management in case it went over your head.

For some, perhaps most, the acceleration in growth may scare you when and if you get there.
You can simply require 5k for any new contract size increases... or whatever amount that suits your risk performance & personality.
The key is making it fit you personally... that's key.
