Fiverr is decreasing my order completion rate automatically daily by 1 point from last 10 days even i completed 1 order in between this time period. i just cancel an order 10 days ago after that fiverr decreasing my rating by 4 points and now my rating is 86 without any reason.
It’s not without any reason. It is clearly stated that your Order Completion Rate is calculated over the past 60 days. When orders become older than 60 days, they will no longer be counted as part of your Order Completion Rate. Thus, you will experience your Order Completion Rate changing even if you get no new orders.
Try calculating it for yourself. It is simple math, and I’m sure it is going to add up.
