The thresholds will vary depending on the environment. The current thresholds are tailored toward a minimum suggestion. If you do update the thresholds, we'd love to hear how you've fine tuned it for your environment, and the type of deployment. There's a feature request that's being tracked to provide threshold suites based on different customer environments (i.e. office, education, higher ed, hospital, airport, etc), but it's based on getting feedback from the field.
