I am risking a demotion from level 1 because my order completion rate is (so far) 88%. I have not managed to recalculate it. The way I see it should be the percentage of completed orders against total (completed + canceled) orders.
I did not manage to replicate the calculation, probably because I am looking at the wrong time period. When do the sixty days start? I tried to calculate them on a rolling calendar basis (i.e. September 10th, Nov 9th) or from each month evaluation date (i.e. starting from September 15th) and I did not manage to replicate the results. I have orders that should be completed before Nov. 15th so I could be fine but I would like to understand how that fairly important percentage is calculated.
I never had any problems with math but I think the FAQ give the wrong information: (Completed+cancelled) divided by canceled multiplied by 100.
In any case, without knowing exactly the time period to consider, it is difficult to check. The Analytics only report 30 days or 3 months and they are about a week behind.
I am not complaining, I’d like to understand
