Why is there no video quality setting for the 500-600 range?

Question

So we all know 144p, 240p, 360p, 480p, 720p, and 1080p. But why is there no setting for something like 550p?

Answer 1

You will notice that these go up roughly (in most cases exactly) in a 1:1.5 ratio. In other words each jump improves horizontal resolution by 50%

So an extra resolution between 480 and 720 would be an anomaly.
