Hello,
I think you're talking about "Power est." column. quote from the source
code
/*
* only report power numbers once we have 3* more measurements than
* we have parameters; anything less and our model fit is highly
* suspect
*/
so powertop need some number of previous measurements in order to start
estimating.
