Your conditions seem fine to me.

Most humidity sensors suck anyhow unless its a high end one like those used for humidors.

The only way to get them exactly where you want the humidity levels is with proper equipment...ie....humidifier / dehumidifier.

Again, your values seem fine and I wouldnt worry bout them.
