Atomic Habits is a very popular self-help book filled with similar nonsensical charts.

Here’s the punchline: If you get one percent better each day for one year, you’ll end up thirty-seven times better by the time you’re done.

1% improvement every day is ridiculous: Start bench-pressing 50kg today and in a week 70kg and in a year?

I guess saying that if you work on something you will eventually be better at it isn’t sexy enough for a book.

But why put the decline into the same chart? If you would plot them separately you would see they are just inversed.

Handrawing the chart is a nice touch as well.
