Individual estimates accuracy report on Jira

Question

I would like to know how accurate I am estimating user stories.

I log my time in Jira + Greenhopper and I had a look to time tracking reports but I'm not sure of how to filter stories by individual user

Answer 1

I get all the stats I needed by creating a simple application which connects to the Jira REST API using their Jira REST Client.

Writing a Jira plugging could be also a solution but I think is far more complicated.
