The derived refresh rate of the repeat combinator is the refresh rate of the child if it is unstable.
Otherwise, the refresh rate is the embedded rate time minus the start time.
In case of the \cleaninline{rpeat} task, the default refresh rate is $\rewriterate{0}{0}$ so the task immediately refreshes and starts the task again.
