Train hard and improve your skills, or stop training and forget your skills. Training just enough to maintain your level is the worst idea.
You reinforce your biases, which makes it harder to resume improvement later. Also, you get comfortable with being at a fixed level.
Also, there’s usually not a good reason to stop at a particular level of skill. If the skill is worth having at all, it’s probably going to be worth having at the highest level you can achieve, and if it’s not worth having, continuing to train to keep the same level at it is probably a manifestation of the sunk cost fallacy.
