On my analytics page it is showing I have 10 cancellations that go back 60 days.
I checked my last ten cancellations, and to get 10 cancellations I had to go back 63 days.
I’ve been watching my completion rate go up and down for no apparent reason in the past week. I wanted to know why, so counted back through the ten cancellations it is counting, and found it actually is going back 63 days. If it went back 60 days, I would have nine cancellations.
Check on your cancellations and count back 60 days to see if the right number are included in the past 60 days.
You can then count the number of orders you had in the last 60 days and get a correct completion percentage.
Also, if your number of orders is dropping in the recent couple of weeks but your cancellations in the last 63 days remains the same, you can get less than 90% completion rate simply due to not getting many orders in recent days.
It looks like you can lose a level simply by not having many recent orders for this reason. So if you go on vacation, your completion rate can drop below 90% just because you are not getting new orders.
You will need to make sure you time your vacations so that if you are gone and not getting orders it does not make your completion rate drop below 90%.
It is quite possible that a two week vacation or even a one week one will put your completion rate below 90%.
My completion rate is dropping not due to new cancellations, but due to not having many new orders in recent days.
