The measurement was done via a smart plug running tasmota (and the tasmota exporter) so I'd say it's pretty realistic.
I also have an HP MicroServer Gen8 with a 20W Xeon cpu (https://www.intel.com/content/www/us/en/products/sku/53401/i...) and four disks... It also idles at ~21W (again, as reported from tasmota-based smart plugs).
