No. I want to find the minimum period at which T at a lower setting is
convenient.

We are not sure setting T at 60° for few hours is more efficient than
letting it at 98° and consume just the keep warm rate. Or setting it Off
for 6 hours, or at 90° or at 80°. The other three settings available on the
kettle.

Producer publishes the keep warm average power consumption with 4l of water
and 20° outside T:

T° C	Wh
98	49
90	43
80	35
60	23

With some approximation I can calculate the energy required to re-heat to
target T. And compare with the above. Improvements to this stub method?
