How much accuracy is overfitting?

If our model does much better on the training set than on the test set, then we're likely overfitting. For example, it would be a big red flag if our model saw 99% accuracy on the training set but only 55% accuracy on the test set.

Is 86 accuracy good in chess?
I'd say for me, anything over 80% leaves me feeling pretty good about my play. For a game that is at least 25 moves long where most of the moves were not forced, I would have to say that 90%+ accuracy (expert strength or better) is generally an indicator of a good game.

Does fov affect accuracy?
The wider the FoV, the smaller the enemy on the screen, so you need to be more accurate to hit them. A low FoV helps your focus. Everything on the screen is bigger, so it is easier to focus on where you are aiming.

Is 99 accuracy overfitting?
If your classifier is "99% accurate", either you're using the wrong metric (a metric this high is not informative), or you have an overfitting or leakage problem. Metrics are feedback points on the way towards better models.

Is smaller accuracy better?
Accuracy allows you to have some idea of the quality based on specific inputs, but small accuracy variations don't always mean better or worse quality in the real world.
