Another example to understand better (I hope):
Imagine your horse was 50 green in speed, because his real value was 5045.
The final value is 5565, that's why it was green.
But with one training your horse won +0.2, he became 5065. So he turned into yellow (still 50, for you, as you only see an average speed).
In my example, it will become 55 yellow than 55 red later.
Is it ok now ?
