Here is a better version of the workload chart btw, with a description what we are seeing on the x and y axis:
I do however agree that calling this chart the “workload” chart is misleading. Since it shows number of items in the SRS, not the number of reviews. . We would have to create a chart that is also based on hours instead of weeks to see how different our charts would look to the original workload chart. Everything looks more drastic when it starts and ends at 0.
