I would like to recommend the addition of fragmented hours (and working hours) to the query designer as a selectable metric like focus hours. I know that fragmented hours is located in the explore area and is pseudo-calculated in PBI templates. However, I would like to see the actual measured value for each person be able to be extracted and reported on. It is not reliable to use workday span and subtract meeting hours and focus hours to calculate fragmented hours. Therefore it would be great to get one or both of fragmented hours and or working hours so we can back calculate the other.
My definition of fragmented hours would be less than 2 hours not in meetings during working hours to make it similar to focus hours. It would also be great to keep the similarities with focus hours and add an uninterrupted fragmented hours option as well in which a collaboration activity was not done during this time period.
