Refresh rate for Download speed

Hi Everyone,

Is there a way to set the refresh rate of the download speed (long press on battery icon) to 1sec or less?
The refresh rate is set by default to 5sec so not very convenient while checking the download speed.
I've also set 1sec in activity monitor but that does not affect BTT widget.

Thank you in advance for your help?

Anybody with a solution? @Andreas_Hegenber any suggestion?
