Tor fails to start if RelayBandwidthRate < 75 KB/s despite torrc stating minimum is 20 KB/s

Tor fails to start if RelayBandwidthRate < 75 KB/s despite stated minimum in just above where this value is set in /etc/tor/torrc:

## Define these to limit how much relayed traffic you will allow. Your
## own traffic is still unthrottled. Note that RelayBandwidthRate must
## be at least 20 kilobytes per second.

and on some web documentation (General Tor FAQ,

"The minimum BandwidthRate setting is 20 kilobytes per second."

Excerpt from /var/log/syslog:

[warn] Failed to parse/validate config: RelayBandwidthRate is set to 20480 bytes/second. For servers, it must be at least 76800.
[err] Reading config failed--see warnings above.
systemd[1]: tor@…: control process exited, code=exited status=1
systemd[1]: Failed to start Anonymizing overlay network for TCP.
systemd[1]: Unit tor@… entered failed state.

Tor starts properly when RelayBandwidthRate >= 75 KB/s.

Suggest changing recommendation in default torrc file comments and on web rather than lowering minimum allowed RelayBandwidthRate.
