One piece of feedback: combining threshold and 'time to threshold' seems to make things more confusing. For example, when you select sum as an output, you also get the sum of the time to threshold. That result -- like "time_to_threshold": 92.7864 -- seems to be simply the sum of hours for the members of the cohort. Knowing that it took the cohort a combined 92 hours to reach the threshold isn't very actionable.

So.......what are you proposing? separating it as two separate metrics? 

Separating is probably the simplest thing to do, but you could also just remove Sum as an output for time to threshold. The two metrics can make sense together, if you check out a result like:
        "Average": {
            "threshold": 0.1735, 
            "time_to_threshold": 0.7863
        }
