Hi David, `CHO Used` has stopped being calculated on my recent cycling activities. I’ve now seen it on multiple rides from different sources: Wahoo ELEMNT outdoor rides and ROUVY indoor rides. Power, duration, kJ, training load and VI are all present, and the `CHO Used` field is still displayed but shows no value. I also tried **Re-analyse activity** , with no change. Older comparable activities were calculated normally. Has anything changed recently in the CHO calculation, or could this be a regression? Thanks! ---

That’s intended, it was never really reliable. > [@Carb utilisation and ingestion on activities](https://forum.intervals.icu/t/carb-utilisation-and-ingestion-on-activities/78676/124): > > We have disabled our current calculation, it seems it doesn’t work well for too many people. Carbs used is now an editable field in the UI and elsewhere. Custom activity fields and apps can update it so people can implement their own calculations.
