As a reflection of travellers' reliability, the delivery rate measures the likelihood of requesters receiving their item from the traveller making an offer.
The delivery rate is calculated as the number of completed requests out of total offers made(completed requests + cancelled requests). Cancellation of a request will not count to the traveller's delivery rate if deposit has not been made for that request. The delivery rate is updated at the point of completion (i.e. Payment Released by requester), or cancellation.
Calculations begin from April 2017 onwards.
