Calculate average time to accumulate to a value.
Consider a dataset like this:
Person | Topic | Points | Date
--------- | ------- | -------- | ------
John | Foo | 80 | 2020-09-10
John | Foo | 40 | 2020-09-12
John | Bar | 63 | 2020-09-14
Sally | Bar | 60 | 2020-09-16
Sally | Foo | 90 | 2020-09-16
Sally | Foo | 110 | 2020-09-18
Assuming the dataset is much larger with more people topics, points and dates, I'd like to be able to plot a vertical box graph of duration (y-axis) for each person to accumulate X (e.g. 100) points for each topic (x-axis). So for each box plot (for each topic), I should see a spread of durations it took for each person to accumulate X points.
I'd ideally like to do this with Beast Mode so I can adjust timeframes meaning I can't build point accumulation into a dataflow.
