A few days ago I completed 3 orders on Fiverr. But those 3 orders were late delivered due to which my on time delivery rate was reduced. After that I again delivered 2 orders on time, when my on time delivery rate was 44%. After that now 1 order is running active in my account, which has time to deliver and I will deliver it on time. But in these 2 days, my on time delivery rate is automatic reduced, from 44% to 38% on the first day and today from 38% to 29%, these days I did not deliver any order, yet the on time delivery rate decreasing. why does this happen?
