Hi all,
I’m wondering if intervals.icu offer sometning similar to the dFRC avaliable in the WKO5?
I know the recovery rate between intervals is quite big approximation but it could be very useful tool 
This is w’bal essentially and yes, intervals.icu can provide an estimate of your w’bal which in turn can be reviewed in post w/o analysis on a custom chart on the activity page or even used when creating a w/o to see when you will of “recovered” between intervals.
Your w’bal can be updated in the settings page and an estimate can be found on the power page. Note its a manual update, its not yet automated when your w’bal changes.

edit! I read a little about W’ here on the forum and honestly I didn’t expect it will be such deep topic!!!
thank you for explanations.
It looks like very useful tool! In my case the WKO estimate 12400J and intervals.icu 19080J. I wonder where such a significant difference in estimates can come from?
Does w’bal represented in the power page is estimated based on result from calculating the area under the power graph, definite integral… or is it calculated in a different way?
Why my w’bal from the training session has a totaly different distribution comapre to workout assumptions?
